What you say makes good sense, as He does not stick around very well- it

I once spoke with a fellow involved in the deep sea diving business, and he
that vidicon cameras used in the deep habitats used to deteriorate in
a matter of days due to in-diffusion from the high pressure He atmosphere.
had to order custom vidicon tubes made of special glasses for which He
was much lower.
