[ RadSafe ] Detectability vs. Hazard ,uranium in peaches

[Ted de Castro]

As a refreshing counter example:

I had an analytical x-ray user and at that time we had user surveys 
being done weekly and as the "supervisor" of the x-rays for her 
department it was her job to survey all the machines each week.  She did 
this herself and therefore personally experienced all those 0 readings 
(ALL of our x-ray machine were interlocked ENCLOSED during routine use 
WITH alarming area monitors telemetered to me - which of course made 
weekly - or even annual surveys just plain silly).

This made her confident enough of the safety we had achieved that when 
she became pregnant she wouldn't tell any of her supervision so that 
they wouldn't switch her to another job.
