"Radioactive material" refers to substances that contain atoms that are unstable and can release harmful radiation.
Full definition
The iodine is taken up by the active (abnormal) thyroid tissue, but not by any other tissues, resulting in a selective local accumulation
of radioactive material in the abnormal tissues.
The reactor is designed to never be opened on site and thus there is little opportunity for diversion of
radioactive material from operating plants.
But a new study on the radiation emitted by everyday objects highlights the fact that we interact
with radioactive materials every day.
I am a radiation safety professional with over 20 years of experience in oversight of research
using radioactive materials and radiation producing devices.
This generation has altered the composition of the atmosphere on a global scale
through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels.
Coal burning has released and spread around the world more than 100 times
more radioactive material than all the nuclear power plants in the world.
These plans are designed to be safe based on physical and chemical barriers that will
stop radioactive material from escaping for hundreds of thousands of years.
It may be an operational issue, but it's one that is
causing radioactive material to enter the groundwater at levels far in excess of safety standards.
That means 36 states with reactors, hospitals and other industry
with radioactive materials have no place to send much of their waste.
We also represent manufacturing companies, as well as healthcare and academic institutions, that
use radioactive materials and are subject to regulation.
Densely packed pools are highly vulnerable to catching fire and releasing huge amounts of
radioactive material into the atmosphere.
She received training in the safe use of
radioactive materials at the Radiation Safety Office at WSU Pullman and said her experiments involve the smallest amount of radioactivity possible to get research results for publication.
The study, published in the online journal Environmental Science & Technology (ACS Publications), determined the impact of intrinsic colloid formation on increased migration of
leaked radioactive materials in the environment.
Experts from the German Federal Office for Radiation Protection (BFS) argue that transporting very low dispersible material in Type B flasks will be just as safe as flying
other radioactive material in Type C flasks.
Particular attention should be given to protective actions for children, those who are ill, and the elderly and their caregivers; long - term social, psychological, and economic impacts of sheltering - in - place, evacuation, and / or relocation; and decision making for resettlement of evacuated populations in areas that were contaminated
by radioactive material.
Solar energy (99.985 %)-- comes from sun (nuclear reactions in sun) Geothermal energy -LRB-.013 %)-- originates as heat from within Earth from
decaying radioactive material.
Moreover, such materials can be used as precursors for the production of compounds with special properties, which mimic structures those are found in spent nuclear fuel, and will also be of great use in the study of how
such radioactive material migrates in nearby geological environments.

It is noteworthy that, even with the presence of poorly designed nuclear power plants in the past, and in some cases demonstrably sloppy operations, the waste from coal - fired power plants has done far more damage, and even spread more
radioactive material around the world than all nuclear power plants combined, including Chernobyl.
Although the amounts of radioactive iodine, cesium and strontium found in any single location throughout northeastern Japan have been small, the cumulative amount of
radioactive material produced by the plant prompted Japan's Nuclear and Industrial Safety Agency (NISA) on Tuesday to submit a provisional International Nuclear and Radiological Event Scale (INES) level 7 rating for the accident (pdf).
Offsite releases of
radioactive materials contaminated land in Fukushima and several neighboring prefectures, prompting widespread evacuations, distress among the population, large economic losses, and the eventual shutdown of all nuclear power plants in Japan.
Entergy Corp. said elevated levels of
radioactive material found in groundwater at the 2,000 - megawatt Indian Point nuclear power facility north of New York City don't pose a threat to public safety.
The new method, published in Scientific Reports, could dramatically reduce the effective half - life (an indicator of the amount of time it takes to bring
radioactive materials down to safe levels) of long - lived fission products [1](LLFPs) from hundreds of thousands of years to within a hundred years.
In order to contaminate a large area with
enough radioactive material to pose a major health hazard, the dirty bomb would have to be packed with so much cobalt 60 (on the order of a few ounces in this case) that the terrorists would die of radiation poisoning within minutes of exposure to their own weapon.
The improper disposal of a derelict gamma - ray research device at the University of Delhi has resulted in the death of a scrap - metal worker — and drawn scrutiny of how India's academic institutions
handle radioactive materials.
There is a radical option: to filter out as
much radioactive material as possible, dilute what is left, and dump it in the Pacific.
The radiation may come from outside of the body (external radiation) or from
radioactive materials placed directly in the tumor (internal or implant radiation).
It underscores the treacherous path facing any major effort tied to nuclear waste, even when federal officials insist the project was a test that would never
involve radioactive material.
There may well be, as suggested above, a field for the national or private production of such
radioactive materials which will require a pile to produce mate -[39] rials for industrial and other peaceful uses.
Once set up, the group submitted a request to
buy radioactive materials for an industrial gauge, which is common practice in fracking country.
Baxter suggested that the particles fell onto the roadside during the 1960s and early 1970s
when radioactive material was being carried in trailers to the waste shaft.
The group set about their plan by renting office space in Dallas, Texas, where a robust fracking industry regularly
requires radioactive materials for gauges needed in their search for gas and oil deposits.
