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).

Chapter 3 RADIATION DOSIMETERS - IAEA

A guard electrode is usually provided in the chamber to further reduce chamber leakage. The guard electrode intercepts the leakage current and allows it to flow to ground, bypassing the collecting electrode. It also ensures improved field uniformity in the active or sensitive volume of the chamber, with resulting advantages in charge collection.
