6 EQUATIONS OF RADIOACTIVE DECAY AND GROWTH

6.6 RADIOACTIVE DECAY SERIES If a radioactive nuclide is situated in the Chart of Nuclides far from the stability line (for the light elements at Z=N), the daughter nucleus after radioactive decay may be radioactive as well. In nature this occurs with the heavy nuclides in the uranium and thorium decay series (Chapter 12).

The dosimeter selected for this research was the Larson-Davis Spark. TM. 705+ dosimeter. This dosimeter was used because it is capable of measuring and recording dose with four separate noise criteria and capable of sampling at a 1-second interval over 13 hours. (3) The dosimeters were setup as shown in Table 1. The results from the OSHA ...
