Description
Abstract In situ tracing of soil water movement with the D 2 O‐ 24 Na method has been limited by the need to reactivate the 24 Na gamma source frequently (half‐life of 15 hours) in a nuclear reactor. Our laboratory study showed 208 Tl produced the same neutron count rates from vials of D 2 O in dry and moist soil as did 24 Na. The 1.9‐year effective half‐life of 208 Tl in equilibrium with its parent nuclide 228 Th is a significant advantage of 208 Tl over 24 Na. Recent commercial availability of 208 Tl sources now makes in situ D 2 O tracing of soil water feasible for investigators not having access to a nuclear reactor.
