Radiation Exposure: Determine the radiation exposure for the situation in which a person gets an x-ray. The individual weighed 96 kg and the exposure area was 0.75 m2 with an exposure time of 35 msec. The initial x-ray intensity was 0.33 W/m2 and emerging radiation intensity detected by the detector was 0.068 W/m2. How many rads & rems did they receive? How many images of this exposure can they receive in one year and be under the safety exposure limit of 0.325 rems?
