Silicon Solar Cells as Versatile Radiation Dosimeters
The use of a silicon solar cell to measure high-intensity radiation is discussed. The ionization rate in the sensitive volume is determined by measuring the short-circuit cell current, and intensities as low as 10/sup 2/ rad/ hr can be measured. A depth dose curve is plotted for aluminum with a 1.07-Mev electron beam. Minimization of the radiation damage due to very intense radiation is discussed. (D.L.C.)
Abstract In order to study the size distribution of a radioactivity due to radon daughters in the environmental atmosphere, an experimental procedure using filters, ion tubes, diffusion batteries and cascade impactors (CASELLA MK2 and ANDERSEN) is presented. A comparison between the experimental results and a theoretical curve, deduced of the attachment theory of the small radioactive ions on atmospheric particles, is carried out.
