Deuterium is at least as stable as the proton contained therein. Theoretical considerations suggest that the proton may have a very long half-life. Experimentally, protons have not been observed to decay, though. The thereby established lower bound on the proton's half-life is about 10^35 years.

Deuterium Half Life

Deuterium is a stable isotope.
Perhaps you were thinking of tritium, an unstable isotope of hydrogen (1 proton and 2 neutrons on the nucleus).
Tritium has a half-life of 12.3 years and emits a very weak beta particle - changing into He3 (2 protons + 1 neutron)

Hi. Deuterium is a stable isotope. Just a hydrogen atom with a bound neutron.

As Cirric said, Deuterium is not radioactive. Half-life refers to the time required for radioactive decay of half a sample of radioactive material. It is not a property of stable elements.
