WebExperiments with steel demonstrated that molybdenum could effectively replace tungsten in many steel alloys. This change brought weight benefits, since the atomic weight of tungsten is nearly twice that of molybdenum. In 1891, the French company Schneider & Co. first used molybdenum as an alloying element in armour plate steel. WebActual process. 1. Using a lead shield, measure the eluate in a dose calibrator on the Moly setting and record the amount. 2. Measure the eluate without the lead shield on the tech setting and record amount. 3. Divide the amount of moly by the tech to obtain the Mo-99 concentration. What is the T1/2 of 99Tc. 2.1x10^5 years. gatwick escalator death
