As early as 1990 we began exploring nuclear effects, beginning with x-ray film, and later measuring tritium, elemental transmutation, then charged particles and neutrons using solid-state nuclear track detectors.
Hydrogen ( H, H, H) There are three NMR-active isotopes of hydrogen, the spin1/2 protium (1H), spin-1 deuterium (2H) and spin-1/2 tritium (3H).

A tritiated form of 5-indolylmethylhydantoin (5a) has been prepared by combining hydantoin (1) with indole-3carboxaldehyde (18) and the resultant alkene (19) then reduced with tritium gas to give [5,6-3H]-5indolylmethylhydantoin (5a) (Figure 4, Scheme 5).
