Document Summary
12 to time is measured starting be can ratio used of to by. 4,2c measure anything made of organic matter comparing ratio of clue in organism. A - 4yz - z t a t energy: x parent nucleus, y daughter nucleus. Beta decay neutron may decay into a in a process called beta - minus proton decay by ejecting an electron. Yz + a t e - t energy some nuclei can also lose a proton by emitting the positron which is the positive antiparticle of the electron: beta plus decay : + energy: beta decay also releases a neutrino which has very small mass. Gamma decay emission of a high energy photon. Daughter nuclei nuclei are nuclei usually usually null radioactive produce their own daughter stops when stable isotopes are produced. Dose absorbed dose of radiation is the energy of ionizing radiation unit: a gy compared is of absorbed per. A- gy of alpha relative biological effectiveness tissue.
