[ RadSafe ] [Radsafe] A guideline on radioactivity in concrete?

[Brennan, Mike (DOH)]

Good luck:  Some years ago I proposed that tritiated water be disposed
of by using it in concrete for freeway barrier and bridge abutments.  It
was dismissed out of hand, with the reason given children might knock
chips off of the concrete and eat them (I think that the actual reason
it was rejected was that the people in charge didn't want there to be
any possibility that something radioactive be viewed as a resource
rather than a waste.  This was the same group that, when they found out
that the Co60 at a particular site was going to have decayed to below
detectable before the site was scheduled to be cleaned up declared, "For
the purposes of calculating clean-up levels, radiological decay does not
occur.")

Dear all,

I am trying to compile the list of different approaches used in
regulating the amount of radioactivity one may have in concrete, road
building material etc.  Basically, the idea is to blend the sand waste
with cement etc to a certain level and make up some blocks that will be
used to prevent beach erosion.  After the manufacture no exposures are
expected except for the fish and for some random diver...
If you could point me in the right direction it will be very much
appreciated.  Most available documents are either:
a) addressing building materials for human habitation, or
b) having radon exhalation taken into account, or
c) both.
Thanks in advance

Kind regards
Nick Tsurikov
