Why is it important to make sure a CT scan is a) medically necessary and b) if it is, that the radiation exposure is kept as low as possible?
In a huge multinatl study that included nearly 1 MILLION kids, adolescents/young adults, CT scans were associated with an ⬆️ risk of blood cancers.
⭐️ “For every 10K children examined today (mean dose 8 mGy), 1–2 persons are expected to develop a hematological malignancy attributable to 1/2
radiation exposure in the subsequent 12 years.
⭐️ ”Our results showed a clear dose–response between cumulative ABM dose
and risk of blood malignancies, both lymphoid and myeloid…
⭐️ Note: Unlike CT, MRI and ultrasound do not emit ionizing radiation. Consider these imaging modalities, if appropriate.
Solar #flares are flashes of #solar #radiation powered by magnetic reconnection.
Many solar flares are accompanied by immense eruptions of magnetized #plasma called coronal mass ejections.
But one type of solar flares come with a coronal mass ejection, while others do not.
Part of the reason could be that that magnetic reconnection happens more rapidly in the former type.

#Fukushima Up Close, 13 Years Later
by Robert Hunziker
October 13, 2023
"The world is turning to #NuclearPower as a solution to #GlobalWarming, but it is postulated herein that it is a huge mistake that endangers society. One #nuclear #meltdown causes as much damage over the long-term as a major #war. Moreover, according to Dr. #PaulDorfman, chair of the Nuclear Consulting Group, former secretary to the UK Scientific Advisory Committee on Internal Radiation: 'It’s important to understand that nuclear is very likely to be a significant climate casualty.'
"#BeyondNuclearInternational recently published an article about the status of Fukushima as well as an exposé of how the nuclear industry gets away with responsibility for #radiation-caused (1) deaths (2) chronic conditions like #cancer (3) #genetic deformities: A Strategy of Concealment, September 24, 2023, by #KolinKobayashi, who is a Tokyo-born France-based anti-nuclear #activist journalist also serving as president of Echo-Exchange. Kobayashi’s work was posted by CounterPunch under the title: How Agencies That Promote Nuclear Power Are Quietly Managing Its Disaster Narrative.
"The following synopsis, including editorial license that adds important death details which defy the nuclear industry’s bogus claims about nuclear safety, opens closed pathways to what’s really going on.
"After thirteen years, the declaration of a State of Emergency for #FukushimaDaiichi Nuclear Power Plant still cannot be lifted because of many unknowns, as well as ubiquitous deadly radiation levels. The destroyed reactors are tinderboxes of highly radioactive spent fuel rods that contain more cesium-137 than eighty-five (85) #Chernobyls. Cesium-137 in or near a human body erupts into a series of maladies, one after another in short order, depending upon level of exposure: (1) nausea (2) vomiting (3) diarrhea (4) bleeding (5) coma leading to death.
"The spent fuel rods at the Fukushima nuclear reactor site are stored in pools of water on the top floor of compromised reactor buildings 100 feet above ground level, except for Unit 3 which completed removal of its spent fuel rods in 2019, an extremely slow, laborious process that’s highly dangerous.
"Stored spent fuel rods in open pools of water are the epitome of high-risk. 'If the 440 tonne vessel collapses, it could hit the storage pool next to it. If this pool is damaged, even partially, another major disaster could occur.' (Kobayashi) In that regard, there’s significant risk of collapse in the event of a strong #earthquake. And #Japan is one of the most earthquake prone countries in the world. 'The city (Tokyo) government’s experts reckon there is a 70% chance of a magnitude 7, or higher, quake hitting the capital within the next 30 years.' (Source: Japan is Preparing for a Massive Earthquake, The Economist, August 31, 2023)
"If exposed to open air, #SpentFuel rods erupt into a sizzling zirconium fire followed by massive radiation bursts of the most toxic material on the planet. It can upend an entire countryside and force evacuation of major cities. According to the widely recognized nuclear expert Paul Blanch: 'Continual storage in spent fuel pools is the most unsafe thing you could do.' Paul Blanch, registered professional engineer, US Navy Reactor Operator & Instructor with 55 years of experience with nuclear engineering and regulatory agencies, is widely recognized as one of America’s leading experts on nuclear power.
"#FukushimaDaichi Nuclear Power Plant will remain a high-risk explosive scenario for decades ahead. After all, a program for future decommissioning is unclear and overall radiation guesstimates are formidable. All the structures where decommissioning will take place are highly radioactive and as such nearly impossible for the dangers to worker exposure."

America’s #Radioactive Secret
Oil-and-gas wells produce nearly a trillion gallons of #ToxicWaste a year. An investigation shows how it could be making workers sick and #contaminating communities across America.
"Breathing in this stuff and ingesting it are the worst types of exposure. You are irradiating your tissues from the inside out.”
by Justin Nobel
"In a squat rig fitted with a 5,000-gallon tank, Peter crisscrosses the expanse of farms and woods near the #Ohio / #WestVirginia / #Pennsylvania border, the heart of a region that produces close to one-third of America’s #NaturalGas. He hauls a salty substance called '#brine,' a naturally occurring waste product that gushes out of America’s oil-and-gas wells to the tune of nearly 1 trillion gallons a year, enough to flood Manhattan, almost shin-high, every single day. At most wells, far more brine is produced than oil or gas, as much as 10 times more. It collects in tanks, and like an oil-and-gas garbage man, Peter picks it up and hauls it off to treatment plants or #InjectionWells, where it’s disposed of by being shot back into the earth.
"One day in 2017, Peter pulled up to an injection well in #CambridgeOhio. A worker walked around his truck with a hand-held #radiation detector, he says, and told him he was carrying one of the 'hottest loads' he’d ever seen. It was the first time Peter had heard any mention of the brine being #radioactive.
"The Earth’s crust is in fact peppered with radioactive elements that concentrate deep underground in oil-and-gas-bearing layers. This radioactivity is often pulled to the surface when oil and gas is extracted — carried largely in the brine.
"In the popular imagination, radioactivity conjures images of nuclear meltdowns, but radiation is emitted from many common natural substances, usually presenting a fairly minor risk. Many industry representatives like to say the radioactivity in brine is so insignificant as to be on par with what would be found in a banana or a granite countertop, so when Peter demanded his supervisor tell him what he was being exposed to, his concerns were brushed off; the liquid in his truck was no more radioactive than 'any room of your home,' he was told. But Peter wasn’t so sure.
"'A lot of guys are coming up with #cancer, or sores and skin lesions that take months to heal,' he says. Peter experiences regular headaches and nausea, numbness in his fingertips and face, and 'joint pain like fire.'
"He says he wasn’t given any safety instructions on radioactivity, and while he is required to wear steel-toe boots, safety glasses, a hard hat, and clothes with a flash-resistant coating, he isn’t required to wear a respirator or a dosimeter to measure his radioactivity exposure — and the rest of the uniform hardly offers protection from brine. 'It’s all over your hands, and inside your boots, and on the cuticles of your toes, and any cuts you have — you’re soaked,' he says."

Today in Labor History, October 30, 1961: The Soviet Union detonated the Tsar Bomba, the most powerful explosive device ever detonated. Soviet physicist Andrei Sakharov oversaw the development of Tsar Bomba, which Khrushchev initiated when the Soviet resumed nuclear testing after the Test Ban Moratorium. The bomb was dropped by parachute from an aircraft, and detonated at an altitude of 13,000 feet. In 1991, Soviet scientists revealed that the actual yield was 50 Mt (209 PJ).

Taylor: "you can't set a radiation protection standard on purely scientific facts alone."
Time has proved Gofman's points
When a particle decays and spits off some alpha radiation why doesnt it take with it some of the electrons from its parent particle? I would expect the electrons to "stick" to the helium nucleus and travel with it.
I am guessing it is a matter of moment. The alpha particle flys off at such speed the resting moment of the electrons may make it so they cant follow it... but considering that electrons arent at "rest" and that they have very very little mass I question myself on this answer.
Turns out we are all getting fracked....

‘Substantial’ safety violation alleged at SC #NuclearPlant after 20 years of problems
by Sammy Fretwell
Sat, October 7, 2023 at 10:17 AM EDT
"Federal regulators have cited #DominionEnergy for what they say is a substantial safety violation after finding that utility workers failed for 20 years to resolve cracking problems at the company’s #VCSummer nuclear power plant northwest of Columbia.
"This past week, the U.S. Nuclear Regulatory Commission issued what’s known as a preliminary 'yellow’ safety assessment, a measure of how serious an atomic safety problem is considered at a power plant. Yellow assessments are the second most serious on an NRC scale of severity.
"The NRC, which rarely issues yellow findings, said nuclear plant operators did not resolve cracking problems from 2003 to 2022 in V.C. Summer’s diesel generator system, one of the most important backup safety systems at an atomic power plant.
"NRC officials were not available Friday to explain their concerns with the backup diesel generator system, but an Oct. 4 enforcement letter to Dominion nuclear operations president Eric Carr said the utility violated an atomic safety standard that could result in more scrutiny of the power plant.
"'We are considering escalated enforcement for the apparent violation,’ according to the letter signed by LaDonna Suggs, acting director of the NRC’s division of reactor projects.
"That’s no surprise to one nuclear safety advocate. Yellow designations often spark additional investigation and scrutiny of atomic power plants like the one in Fairfield County, said #DavidLochbaum, a former NRC official and expert on the inner workings of nuclear plants.
"'The NRC feels this was avoidable,’ Lochbaum said, when asked why the agency issued a yellow finding. 'There were signs of problems that were overlooked. Because of that, the problem grew to a point where the diesel generator' system did not work during testing.
"'You’re supposed to find and fix problems that occur,’ he said.
"Since 2009, the NRC has issued seven yellow findings against the nation’s nuclear power plants, Lochbaum said, after reviewing agency records. Only a red designation is considered worse, with white and green findings less significant. The United States has nearly 100 nuclear plants.
"The NRC’s determination is not final and is listed as an 'apparent’ violation. Dominion will have an opportunity to explain more about the diesel generator system issues, according to the NRC. Dominion spokesman Darryl Huger said the company 'has implemented a plan to improve the system’s reliability.’
"Huger, in an email to The State, said V.C. Summer has a history of operating safely, maintaining what he said was an 'exemplary’ record. The recent NRC concern centers on a pipe that delivers fuel to one of the power plant’s two emergency diesel generators, he said. Dominion found problems after testing the piping system, according to the NRC.
"Dominion’s backup diesel generator system, like those at other nuclear plants, is designed to provide power to parts of the plant that need electricity in the event power is knocked out during an emergency, such as a storm or earthquake.
"That’s important because power is needed to keep water running through the nuclear reactor core to prevent it from overheating. If power is lost, the nuclear fuel can melt, causing #radiation to be released into the surrounding community.
"In this case, officials at the V.C. Summer plant learned about #cracks in fuel pipes in the facility’s diesel generator system in 2003. Utility workers fixed the initial crack, as well as other cracks four different times in the years after the initial work was done.
"But the NRC says the utility never adequately assessed what could be done to make sure the diesel piping system did not experience more cracking. The most recent cracks were identified in November 2022 during a 24-hour test of the system. Workers found a small leak on one of two diesel generator systems. The leak increased over time and workers discovered a 140-degree crack around a pipe, records show.
"The cracking occurred mostly in the power plant’s 'A' diesel generator system, although one problem occurred in the plant’s 'B' generator system. The plant has two backup diesel generators.
"The cracking that led to the yellow safety finding follows separate, electrical problems with the plant’s diesel generator system in 2022. The NRC said the company, in that case, also failed to promptly resolve problems, issuing a white finding last year. White is lower in safety significant than yellow, but still considered notable.
"Tom Clements, a long-time nuclear safety advocate, said the NRC’s recent yellow safety assessment reveals a violation 'too egregious to ignore.’ He called for a 'severe monetary fine’ against Dominion, which he said ignored preventative maintenance through the years.
"Dominion’s problems are noteworthy in light of the company’s recent request to renew its V.C. Summer operating license another 40 years, Clements said. The power plant, which cranked up operations in the early 1980s, is about 25 miles northwest of Columbia in rural Fairfield County.
"'Hopefully, serious safety problems don’t lurk in other reactor safety systems at the reactor,’ Clements said in an email to The State. 'This incident serves as a wake-up call to fully analyze all such systems prior to a license-renewal determination.’
"The power company, which acquired former V.C. Summer plant owner SCE&G after a failed effort to build two additional reactors at the site, plans to install thicker piping in the generator system, Huger said."

Wild boar in Eastern and Central Europe have remained highly radioactive since the Chernobyl nuclear disaster.
Scientists have determined the ongoing high levels of radiation relate to the boar's preference for deer truffles. This article details how the dynamics of deer truffles and the #ecosystem they are in enhances the contamination of the #truffles, and their ongoing threat to health.
So these truffles are not just increasingly absorbing #Chernobyl #radiation, but also fallout that spread globally from nuclear weapon testing.
As the old saying goes, we know when #nuclear disasters start, but not when they end, because they don't end.

After talking to my mom:
While iPhone 12 ”radiation levels” is correctly used language, too many people don’t know the difference between electromagnetic #radiation and ionizing radiation, as made evident by some articles illustrating the France story with the warning sign for ionizing radiation ☢️
A more responsible communication would have been to say that the levels of (electromagnetic) emissions are too high.

#Palisades #nuclear plant gets $150 million in #Michigan budget
By Sheri McWhirter, Jul. 03, 2023
"Michigan lawmakers included $150 million toward the effort to restart the Palisades nuclear plant as part of a record $81.7 billion state budget passed last week.
"State officials contributed the millions in taxpayer dollars toward #Holtec International’s effort to get the nuclear plant upgraded and fired back up to provide 800 megawatts of carbon-free, base load power as the energy sector transitions away from fossil fuels. If it happens, it would be the first nuclear plant nationwide to return to generating power after being decommissioned.
"The plant was closed last year when its fuel ran out and the owner sold the facility to Holtec. The new owner has now twice applied for federal money to help get the plant operational again.
"The Biden administration has a $6 billion fund within the U.S. Department of Energy intended to preserve the U.S. nuclear reactor fleet and energy sector jobs.
"[...] Power generation at nuclear plants does not generate greenhouse gas emissions that drive climate change, like burning fossil fuels does. However, some #environmental advocates remain concerned about ecological #degradation from needed #uranium #mining and #radiation risk from #ToxicWaste nuclear plants produce."

"It's in your teeth. Your eyes and your brain too. Scientists call it the "bomb spike" (or "bomb pulse") – and for more than half a century its signature has been present inside the human body.
In the 1950s, there were so many nuclear bomb explosions above ground that it transformed the chemical make-up of the atmosphere – altering the carbon composition of life on Earth ever since, along with oceans, sediments, stalactites and more."

"According to the International Atomic Energy Agency (IAEA), the UN’s nuclear watchdog, nearly 13 million people are exposed to ionizing radiation in occupational settings every year worldwide. There are horror stories within the nuclear safety community of what can happen with lax institutional oversight of nuclear and radiological materials—from stockpiles of improperly managed radiological waste to missing or inaccurate inventories to lost or destroyed records."

Unlike many other lost source incidents (Goiânia Brazil, Tammiku Estonia, Samut Prakarn Thailand, Li Georgia) which are documented in fascinating detail on the IAEA site, there is very little information available on this particular accident.
But they do mention the source had a 1800 R/year dose rate. Interestingly, this works out to 2 mSv/hr which is exactly the same as was quoted for the WA source.
The other day, a friend of mine pointed out that the missing cesium capsule in Western Australia is the same kind of capsule as the one that led to the Kramatorsk incident in Ukraine in the 1980s, in case you wanted context on how absolutely dangerous this tiny thing is.
