Counts per minute dose reading. This modifies the tube characteristic so each count resulting from a particular radiation type is equivalent to a specific quantity of deposited dose. More can be found on radiation dose and dose rate at absorbed dose and equivalent dose. Disintegrations per minute (dpm) and disintegrations per second (dps) are measures of the activity of the source of radioactivity. The SI unit of radioactivity, the becquerel (Bq), is equivalent to one disintegration per second. This unit should not be confused with cps, which is the number of counts received by an instrument from the source. One dps (one dpm)
Induced radioactivity Induced radioactivity Induced radioactivity, also called artificial radioactivity or man-made radioactivity, is the process of using radiation to cause a previously stable material to become radioactive. The husband and wife team of Irène Joliot-Curie and Frédéric Joliot-Curie (they both began using the surname Joliot-Curie when they married in 1926) discovered induced radioactivity in 1934, and they shared the 1935 Nobel Prize in Chemistry for this discovery. Irène Curie began her research with her parents, Marie Curie and Pierre Curie, studying the natural radioactivity found in radioactive isotopes. Irène and Pierre Joliot-Curie Irene branched off from the Curies to study turning
