Erm, rubbish - again!

so poses very little hazard.


What has the half-life got to do with the hazard?

Becaise it doesn't hang around being radioactive. Created by cosmic rays
in upper atmosphere, and turns to deuterium or hydrogen by the time it
gets to the surface?

Radoactivity is a fact of life. Its only when its in heavy
concentrations, or associated with substances that get incorporated into
the body structure, that it ooses serious risks.

Low l;evel tritium presumable occurs as heavy water, and teh body is
constantly excreteing that so it won;t stock.

Contrast a flake of inhaled plutonium stuck in the lungs, forming a nice
radioactive hots spot exactly wheer cancers are prone to form..and not
decaying for hundreds of years either, and poisonous to boot.
