Many industry members advocate a standard that would allow for the release of all metal estimated to give off doses of radiation at 10 to 15 millirems per year.
Although the new standards woudl recognize for the first time that fetuses are more vulnerable to radiation than adults, the recommended standard for pregnant women, 500 millirems per year, may be five times too high for fetuses in the first trimester.
One sievert = 100 rem; 1 mSv = 100 millirem (mrem).
The 1976 levels were: 5 picocuries/Liter for the radium isotopes and 4 millirems for the beta/photon emitters.
After measuring radioactive material across Bikini Atoll, researchers determined the island produces an average of 184 millirems of radiation per year.
Subpart H is therefore intended to limit radionuclide emissions (except radon) from the stacks and vents at DOE facilities to ensure no member of the public receives an effective dose equivalent to more than 10 millirems per year (mrem/yr) or in SI units 0.1 millisievert per year (mSv/yr).
The 50 picocurie per gram limit comes from a health department-commissioned study by Argonne National Laboratory, which found a landfill worker exposed to TENORM at a rate of 51.6 picocuries per gram could reach the recommended limit of 100 millirems per year.
receive around 310 millirems (mrem) of "background" radiation each year.
The dose of radiation that one gets with a chest x-ray is so minimal, about 30 millirems, which is even less than the radiation exposure one gets from travelling by air (where you will be exposed to a greater degree of radiation from the sun) for a 4-hour flight, say to another Asian country.
(56) Lowering of standards might also raise questions with the timing for the change in the allowable standard for radiation dose per screening from 10 millirems in 2002 to 25 millirems in 2009, the standard allowing more radiation per dose by two and a half times from the 2002 (57) standard to the 2009 (58) standard.
Exposure to radiation can be measured in minute particles called millirems (mrem).
