Tritium Fact Sheet - Health Physics Society

Tritium can also be “sniffed” or introduced into an ionization chamber that can measure radiation dose rates. The difficulty in detecting tritium has led the EPA and NRC to limit tritium releases , as discussed above.

CHAPTER 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.
