In my experience people don't want simple efficient solutions to the
problems of radioactive materials. They want CYA solutions that will
never be questioned by regulators or activists. So, $1000 is a small
fee to pay for secure certain no-issues disposal. As an example, a
client once asked for a survey of a rail gondola car that had tweaked
the meter. The gamma spec and further investigation (more than $1000)
verified that the material was railroad ballast (granite that was
naturally radioactive) lodged in the bottom of the car. The realistic
simple answer to the "problem" was that it was natural material. So,
don't worry about it. The state (not Hamrick) did not like the solution
and the car went onto a siding in limbo, later to be combined with
others of like condition to be cleaned at great cost by the railroad.
CYA achieved. Dumb!
An airline called. They had a stain of I-131 on the tarmac from a spill
that had been cleaned up. What to do? The simple solution: cover it
with steel plates long enough to decay, then remove the plates. The CYA
implementation: remove the asphalt and send it to Utah at great cost.
It is really hard to convince people to believe that the radioactivity
will go away all by itself. CYA - send it somewhere else.
