- It is important to recognize that ionizing radiation is continuously present in our environment. This “background”radiation exposure includes cosmic rays, radon, radiation from terrestrial rock, and natural radionuclide. The amount of background radiation is location dependent. Some neighborhoods
have higher levels of radon in their basements than others. People living in high altitude are exposed to
more cosmic radiation. People living in the mountains are exposed to more terrestrial radiation from the rock in the mountains. . - THE GENETIC DOSE TO WHOLE POPULATION SHOULD NOT EXCEED 5 REMS OVER APERIOD OF 30 YEARS
- International and National Radiation Safety Agencies have set standards that allow a maximal exposure limit of 50 mSv/year for those who routinely work with radioactive material.8 It is useful to discuss medical radiation exposures within the context of background radiation exposure
- .Another way to look at medical radiation dose compared with background radiation dose would estimate that a sinus CT would be equivalent to an extra 2 months of background radiation.
- how much radiation you get
