This is a crazy over-reaction to 4 drums with tritium mixed waste.  Do they have a clue how extremely large the release limits are for tritium?  It's H3 with a weak beta.

That beta is so weak that it's not detected by most, virtually all, field instrumentation. H3 energy is more close to that of an alpha.

Yea, though I walk through the boundaries of containment, I shall fear no dose, for my meters are with me.  My counters, air sample filters, and smears, they comfort me.

??? I don't think so.

Maybe not, I could have a memory error. But I usually think of alpha particles having an energy of about 5 MeV,  and the emitted beta from H3  about 5 keV.

   I can sympathize, I have an increasing number of senior moments myself. I double check facts and proof read a lot more than I use to. But then a retiree does not have to be in a hurry.

   Another example of poor public education by the nuclear sector. May shock some of them to know that the exit signs in their building may be powered by Tritium up to 25 curies and it is still not (or barely) detectable with a standard frisker. Not historical you can still buy them giving you and emergency sign that does not need external power or a battery. Packaged a number of drums of those signs at one DOE site, decay correcting each sign so I could package more signs in each drum.

   Pete I did remember the curie content but did a double check anyway.

Marlin, 😄😄.
Re: using Fisker's for H3... not good. H3 probes are your basic 43-68 w/o the mylar.

   Actually used the listed curie content and manufacture date. Just mentioned the frisker for relative risk communication. Did have to get the RCT to dose rate the full drum to be in compliance though.  8)

Did a D&D on a H3/C14 lab. H3 probes are a pain, a total pain! Boxes of materials at BKG w/ M19.😴

   The project I did with the exit signs also had gallons of tritium contaminated mercury and tritium contaminated sump sludge. Did not do the monitoring or sampling myself so I have no idea what meters/instruments they used, I was an end user of the data. It was the only demo project where I sealed the B-25's with caulking instead of the supplied gasket to prevent off gassing in transit.
   You would think if some of the public were aware of the negligible hazard involved they would be asking if we were spending too much to handle an isotope formed in our upper atmosphere because of the ignorance of the rest of the public.


   Trying to link back up to the public reaction in the OP.

The AF silo folks had a "qualitative" tritium monitor for decades.  Was still in place a few years ago.  When checking for leaks during inspections, the monitor simply note something was or wasn't there.  If something was there, they backed off and contacted their Bioenvironmental Engineering group.

oh!!! I have quite a long story on that detector and using them at an animal research lab DnD and how the ludlum version which was cobbed up by he who shall remain nameless was so easily modified (by moi) to include the discarding of the stupid cap screws and the redneck engineering self stick foam seals, to be replaced by more modern smart appliques (again by moi) which had the other techs extolling ooohs and ahhhhhs and he who shall remain nameless not a happy camper,....


because - that's what I do,.... :P ;) :) 8)

been there, dun that,... the doormat to hell does not read "welcome", the doormat to hell reads "it's just business"
