To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.

When it comes to ionizing radiation, remember time, distance, and shielding: Minimize time spent in areas with elevated radiation levels. ... Maximize distance from source(s) of radiation. ... Use shielding for radiation sources (i.e., placing an appropriate shield between source(s) of radiation and workers).

For reducing radiation exposure, there are 3 principals: time, distance, and shielding. Time. Radiation exposure can be accumulated over the time of exposure. ... Distance. A greater distance from the radiation source can reduce radiation exposure. ... Shielding.

Human exposure to solar UV radiation may result in acute and chronic health effects of the skin (such as skin cancers) the eye (such as cataracts) and the immune system. All skin types can be affected. Natural UV radiation levels depend on sun elevation, latitude and altitude, cloud cover and ground reflection.

A radiation protection program is intended to ensure that all activities and operations involving the use of X-rays are performed in such a way as to protect users, staff, patients and the public from exposure to unnecessary radiation in practices that use X-ray equipment.

The annual radiation dose limit for workers is 0.05 sieverts (Sv) or 5 rem. During an emergency, the guidance for when to evacuate or shelter in place is when the total projected dose exceeds 10-50 millisieverts (mSv) or 1-5 rem over the course of four days.

The OSHA Ionizing Radiation standards (specifically 29 CFR 1910.1096 in general industry and, to the extent it applies, shipyard employment, marine terminals, and longshoring; and 29 CFR 1926.53 in construction) permit whole-body exposure up to 1.25 rem (0.0125 Sv) per calendar quarter, which is often applied in ...
