WebIn cases that radioactive material cannot be contained, it may be diluted to safe concentrations. For a discussion of environmental contamination by alpha emitters please see actinides in the environment. ... Beta radiation, consisting of electrons, is halted by an aluminium plate. WebCHAPTER 4 104 Survey meters come in different shapes and sizes, depending upon the specific application (see Fig. 4.2). The gas is usually a non-electronegative gas in order to avoid negative ion formation by electron attachment, which would increase the collection time in the detector, thus limiting the dose rate that can be monitored.
