WebJan 1, 1994 · The name is derived from "Roentgen equivalent man." Wilhelm Roentgen discovered ionizing radiation in 1895 at about the same time that Pierre and Marie Curie discovered radium.) All of these limits are for the amount of radiation exposure in addition to background radiation and medical radiation. Adult: 5,000 Millirems Webworkers: 5 rem/yr (50 mSv/yr) Dose Equivalent: 100 rem = 1 Sievert = (absorbed dose x radiation quality) Absorbed Dose: 100 rad = 1 Gray. 1 rem . ≈1 rad for x-and gamma-rays ( “ ≈” stands for “approximately equal to”) 0 2000 …
