So ended a life of invention largely unrecognised as biographers of George Taylor and Archibald Shaw claimed all the credit for them for Kirkby’s endeavours. Edward Hope Kirkby was a jeweler watchmaker in Williamstown who eventually became a manufacturing electrician making systems of fire protection, in 1908 he invented and patented the first automatic sprinkler alarm. He is first recorded as experimenting with X-ray in September 1896 This is only 9 months after Roentgen presented his discovery of X-rays. He is reported as experimenting with the medical staff at Williamstown Hospital later that
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
