Re: Decay-In-Storage

We used the principle of decay after the Chernobyl accident in Austria.
Milk, containing I-131 above the limit was diverted and used to manufacture
cheese. Cheese must ripen for a long time, depending on the type of cheese
it might be up to six months and more. Since I-131 has a half life of 3.8
days you can imagine that in the cheese no I-131 was detectable. Applied
Decay-In-Storage!

Jerry P. Lahti pointed out that he had the impression that half-life of
I-131 seems to be different in Austria from the half-live in the USA! No,
there is no violation of basic physical principles, simply I have worked
too much with Rn-222 in recent years, which has a half-life of 3.8 days!

Sorry for that!
