ANS member Dr. Christopher Morrison was a recent guest on The Space Show. Dr. Morrison covered space radiation, lifetime radiation limitations, legal limits, rodent GCR and radiation experimentation, terrestrial radiation simulations, space nuclear power & propulsion, super-cooling conductivity.
The start of Marie Curie's story isn't like most of the other scientists that had made a name for themselves throughout history, mostly because she was a grown woman by the start of the 20th century. But she was the first woman to do a lot of things, including getting a Ph.D. from a university in France, and winning a Nobel Prize. She was also the first person ever to win a Nobel Prize in two different fields of science. To say she pushed the societal and scientific boundaries of her era is an understatement.
As a fourth year nursing student working in Chicago area hospitals, I deal with nuclear medicine quite often. The term "nuclear medicine" can sound disconcerting, but when you are familiar with it, I assure you, it's not. Just think of it as a bunch of necessary medical tools with a little radiation thrown in. I know what you are thinking. Radiation? What? Relax. It's fine. You already know it, and either you, or someone you know, has been exposed to this specific area of medicine via certain procedures.
On Episode 12 of RadioNuclear, we discuss how fear-mongering stories about nuclear power plants in the path of a hurricane are irrelevant, the Oyster Creek Shutdown, and lastly, how nuclear power should be used geopolitically.
Dr. Edward Calabrese recently published a paper titled The Genetics Panel of the NAS BEAR I Committee (1956): epistolary evidence suggests self‐interest may have prompted an exaggeration of radiation risks that led to the adoption of the LNT cancer risk assessment model.
In January, the U.S. Environmental Protection Agency issued an Advanced Notice of Proposed Rulemaking (ANPR) concerning 40 CFR 190-the regulations that govern public exposure and release of radioactive materials resulting from normal nuclear power plant operations (it does not pertain to nuclear accidents). The public comment period for the proposed rulemaking ended on August 3.
On August 3, 2014, the window will close on a rare opportunity to use the political process to strongly support the use of science to establish radiation protection regulations. Though it is not terribly difficult for existing light water reactors and fuel cycle facilities to meet the existing limits from 40 CFR 190 regarding doses to the general public and annual release rate limits for specific isotopes, there is no scientific basis for the current limits. If they are maintained, it would hinder the deployment of many potentially valuable technologies that could help humanity achieve a growing level of prosperity while achieving substantial reductions in air pollution and persistent greenhouse gases like CO2.
A group of past presidents and fellows of the American Nuclear Society has composed an important open letter to ANS on a topic that has been the subject of controversy since before I first joined the society in 1994. The subject line of that letter is "Resolving the issue of the science of biological effects of low level radiation." The letter is currently the only item on a new web site that has been created in memory of Ted Rockwell, one of the pioneers of ANS and the namesake of its award for lifetime achievement.
The Centers for Disease Control and Prevention (CDC) estimates that 1 in 6 people get food poisoning each year in the United States and that 3000 die from foodborne illness. Food irradiation can drastically decrease these numbers by killing harmful bacteria such as E. coli and Salmonella in meat and produce. The U.S. government endorses the use of food irradiation, but does not educate the public about its benefits. Food irradiation has not caught on in the United States because consumers fear that radiation will mutate the food. The U.S. Food and Drug Administration (FDA) requires a label (pictured below) for any food that has been irradiated.
Yes, indeed, you do have one. It's rather surprising that many people simply don't realize that radiation exists naturally all around us, and is part of our everyday lives-whether we are aware or not.
The U.S. Environmental Protection Agency just released a draft Protective Action Guideline (PAG) that sets standards and makes recommendations for the response to a large release of radioactive material into the environment (e.g., from a nuclear plant accident or a dirty bomb attack, etc.). The draft report is now out for public comments (which are due by July 15).
At about a quarter to three in the afternoon on March 11, 2011, a gigantic and unprecedented earthquake struck just over 110 miles off the coast of Fukushima Prefecture in Japan. The quake was followed, just over 40 minutes later, by the first of several rounds of tsunami, which inundated enormous areas and eradicated entire towns and villages. Over 19,000 people were killed or are still missing, and over 6,000 survivors were injured.
All ages are welcome at the Friday Nuclear Matinee for this short video from the UK. Kids get in free! Also, adults who enjoy British accents-and cartoons-and the funny word "aluminium."
Plus a few pointers to what's in store for 2013
With the 2012 American Nuclear Society Winter Meeting wrapping up in San Diego, a musical tribute to the nuclear sciences and technologies-and now, the nuclear arts!- is in order.

As a cancer researcher, I am constantly reminded of the horrific impact that breast cancer has on women and their families. This past week I received notification from my boss informing me and others that a work colleague's daughter had recently passed away from breast cancer at the age of 40-certainly this reminder was much closer to home than usual. It is difficult to imagine the pain and suffering my colleague and his wife are now experiencing, adding to what I am sure was a nerve-racking and exhausting period of consultations for the family and treatments for his daughter.
Science historian Alex Wellerstein recently wrote of a series of nuclear weapons tests conducted in 1955 at the Nevada Test Site, known as Operation Teapot. Among the important civil defense questions explored at the time was: What will the survivors drink after a nuclear apocalypse?
