Betreff: RE: AW: Missing Exit Signs
=================
An insteresting timeline for radiation science and history, including
radiation accidents can be found at:
www.roadtechs.com/rpchron.htm
It includes:
1961 Switzerland a tritium exposure of three individuals up to 300 rem leads
to one fatality.
1964 Federal Republic of Germany, overexposure of four to tritium, doses up
to 1000 rad, 1 death
I was aware that there had been one occupational death, but not of a second.
Because the biological half life of tritium is only about 10 days, it is
very difficult to get a significant dose from an acute exposure. On the
other hand, a small fraction of inhaled/ingested tritium will become bound
in body hydrocarbons and have a much longer biological half life.
Therefore, chronic occupational exposure can lead to a situation in which a
significant fraction of the body's hydrogen in hydrocarbons has been
replaced by tritium.
Like Franz, I too have a paper, citing at least one of the above
occupational fatalities, lost in my archives.
Best regards.

Jim,
I would have been surprised if nobody at RADSAFE would have known more than
I know on tritium fatalities! Thank you for your informations and hope you
share with us the paper if you find it.
Best regards,
Franz
