But hey, it's only SLIGHTLY radioactive-I'm sure it's perfectly good for you!
I hate to break it to you, but your environment is already radioactive, from Radon gas in your basement coming from concrete, to cosmic rays to potassium in your own body:
K-40 occurs in natural potassium (and thus in some commercial salt substitutes) in sufficient quantity that large bags of those substitutes can be used as a radioactive source for classroom demonstrations. In healthy animals and people, K-40 represents the largest source of radioactivity, greater even than C-14. In a human body of 70 kg mass, about 4,400 nuclei of K-40 decay per second.
So stop panicking and accept the Universe for what it is. In addition, the half0life of tritium is 12 years, so it'll all go away pretty soon.
