SafetyRadiation Exposure

Adherence of radiation safety protocolsDental x-rays are one of the lowest exposure of radiation dose

Absorbed radiation is measured in units of millirem(mrem)– In the United States, the average accumulated background radiation

dose to an individual in a 1 year period is 620mrem Radiation itself is measured in units of millisieverts (mSv)

Perspective4 bitewings 0.4 mremChest xray 10 mrem CT scan of head 200 mremCT scan of chest 700 mrem5 hours transcontinental flight 2-5 mremBanana 0.01 mrem1 cup of Brazil nuts 0.016 mrem Living at high altitude for 1 year i.e. Denver, CO 50 mrem per year

Other Common Day-To-Day Sources of Radiation

Televisions with cathode ray tubesFlat screens do not have tube (1 mrem per year)

Drinking water Sourced from rivers and lakes which pick up radiation from natural sources like the soil and rocks (5 mrem per year)

Natural gas stoves (9 mrem per year)Cigarette smoking – quarter of a pack per day (1,300 mrem per year)
