How to use this calculator

Use the calculator below to estimate your yearly dose doseDose is defined as the amount of radiation or energy absorbed by a person's body. from the most significant sources of ionizing radiation ionizing radiationRadiation with so much energy it can knock electrons out of atoms. Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes.. Estimates are given in millirem milliremThe millirem is the U.S. unit used to measure effective dose. One millirem equals 0.001 rem. The international unit is milliSievert (mSv). (mrem) mremone thousandth of a rem, the U.S. unit for effective dose. Effective dose is a measure of the amount of radiation absorbed by a person that accounts for the type of radiation received and the effects on particular organs. (The corresponding international unit for effective dose is the millisievert (mSv).)

According to the National Council on Radiation Protection and Measurements (NCRP), the average yearly radiation dose per person in the U.S. is 620 mrem.
