[ RadSafe ] Panel wants tighter radiation security

So many things to worry about, control, fix... this hardly seems to rate in
the top 100. It also seems odd the Cs-137 would be singled out.
The ICRP's writings on optimization of radiation usage have always struck
me as sensible - consideration of all risks, benefits and costs to
individuals and society are weighed to determine the reasonableness of an
action. Although I have not reviewed details of any analysis of Cs-137
irradiator security, my first thought is that the discussion presented is
short sighted and does not consider energy usage, shielding and interlock
redesigns, training changes, waste storage/disposal, etc. The cost for
small businesses, hospitals and researchers to purchase replacement
equipment might be prohibitive. As a potential (direct or indirect)
consumer, I'm pretty sure this is not how I want to have businesses, health
care organizations and researchers spend money.
Regarding risk, my sense is that Cs-137 is one of the more readily
detectable materials; its moderately long half-life doesn't appear to be a
negative, as this allows for more realistic exposure and hazard assessment,
which would (one hopes) result in more efficient emergency response
activities if they were ever needed (and here's to hoping such response
never will be needed).
