Nettet19. nov. 2024 · Summary There are geogenic and cosmogenic contributions to the radioactivity of rocks. Radioactivity arises from the relationship between the atomic mass number, the number of protons and neutrons, and the atomic ordinal number in a radioactive element. Radioactive nuclei decay according to the exponential law. Nettetfor a radioactive nucleus 1 Ci = 3.7·10 10 decays/s = 3.7·10 10 Bq 1 Bq = 1 decay/s Classical unit: Curie: Ci corresponds to the number of decays of 1 g Radium as introduced by Madame Curie Modern unit: Becquerel: Bq notes a single decay event Example: the human body is radioactive with an activity of: 2.2⋅10-7
