Tritium

H3-2 Characteristics Radioactive half-life: 12.4 years Decay mechanism: Beta emission Energy: Emax = 18.6 keV Eavg = 6 keV Contamination monitoring: Liquid scintillation counter for wipe surveys Dosimetry: Urinalysis

H3-3 Detection Difficulty Because the beta emitted has a very low energy, tritium can not be detected with the usual survey meters found in the lab. Special care is needed to keep the work area from becoming contaminated. Tritium can be detected by doing a wipe survey and counting the wipes in a liquid scintillation counter,

H3-4 Diffusiveness Many tritiated compounds readily penetrate gloves and skin. Wearing two pairs of gloves and changing the outer pair every fifteen or twenty minutes will reduce the chances of cross contamination and absorption through the skin
