The weeklong celebration highlights the radiologic technology profession and raises public awareness about radiologic technologists. The first National Radiologic Technology Week® was held July 22-29, 1979. The annual celebration was later changed to November to commemorate the anniversary of the x-ray’s discovery by Wilhelm Roentgen on Nov.
Roentgen equivalent man Roentgen equivalent man The roentgen equivalent man (or rem) is an older, CGS unit of equivalent dose, effective dose, and committed dose which are measures of the health effect of low levels of ionizing radiation on the human body. Quantities measured in rem are designed to represent the stochastic biological risk of ionizing radiation; primarily radiation-induced cancer. These quantities are derived from absorbed dose, which in the CGS system has the unit rad which is also an older unit. There is no universally applicable conversion constant from rad to rem; the conversion depends on relative biological effectiveness (RBE). The rem
