The biggest source of man-made radiation is a CT scan, which produces views of your body as if they were in slices, layer by layer, to deliver a 3-D image--it can expose you to anywhere from 200 for a head scan to 11,000 mrem for a full-body scan.
11) The EPA states that there is no firm basis for setting a "safe" level of maximum radiation exposure, but we estimate it as the safe occupational dose threshold for workers at nuclear power plants: an additional 5000 mrem of radiation a year above the 360 mrem level, the equivalent of five CT scans a year.
nuclear power plants), the Environmental Protection Agency uses a standard of 25 mrem per year of whole-body dose.
Typical effective radiation doses Typical effective dose Study mrem mSv Skull radiographs 4-20 0.
A full mouth series with 20 radiographs is estimated to deliver <1 mrem.
To put the risk in perspective, firefighters responding to the 1986 Chernobyl disaster received 70,000 to 1,340,000 mrem of radiation.
Over the course of a radiologic technologist's pregnancy, equivalent dose to the embryo and fetus should not exceed -- mSv or-- mrem.
Our exposure ranges from 200 mRem inhaled annually from radon in the atmosphere to 10mRem annually from TVs and smoke detectors, according to Christensen's Physics of Diagnostic Radiology.
Thirteen months later, EPA issued a revised "two-tiered" standard under which maximum exposure beyond 10,000 years will be limited to 350 mrem per year, which is roughly equivalent to the average background exposure for individuals across the globe.
The annual limit on public exposure from a single source of ionizing radiation is 100 mrem (1 mSv), both in the United States and internationally.
Bending to anti-nuclear propaganda, the Environmental Protection Agency set our radiation safety standard ridiculously low, only 15 millirems per year, while residents of Ramsar, Iran, a resort over the Caspian Sea, are exposed to natural radiation of 26,000 mrem per year with no ill effects.
The average person is exposed to about 360 mrem (a unit used to measure the effect of radiation on the human body) a year from Radon, cosmic rays, soil, X-rays, cigarettes and even television.
