WebRadiation Dosimetry The effect of ionizing radiation on matter (especially living tissue) is more closely related to the amount of energy deposited rather than the charge. This is called absorbed dose. Gray is defined as ” The amount of radiation required to deposit energy of 1 Joule in 1 Kilogram of any kind of matter ”. Gray (Gy=J/Kg) is the Standard International … WebOther radiation dose measurement units include rad, rem, roentgen, sievert, and gray. …
Webthreshold for low-LET radiation [3,4,5,8,9]. Others have expressed the opinion that the data have been inconclusive on the question of whether a safe dose threshold exists or not [2,10]. A safe dose and safe dose rate of ioniz-ing radiation (i.e., zero radiogenic risk) means that all exposed persons remain unharmed during and after the exposure. In
