摘要:
Radiation timing device for use in fuzes for bombs, shells, mines and the like. The constant emission of radioactive emanations from a radioactive source is used to measure time. The device consists of a source, a shutter or absorber placed between the source and a radiation detector and counter. When a predetermined number of emanations is counted a switch activates the device.
