X-ray surveys

["Tony LaMastra" <alamastra@enter.net>]

We survey all x-ray equipment annually, including analytical 
(diffraction & spectrographic), microscopes, accelerators (surveyed
quarterly), medical, industrial 
(gauges and radiography).   In addition, all safety warning systems 
(lights, indicators, etc) and interlocks are checked at the time of 
the surveys.  Additional surveys are made following major maintenance 
or disassembly of components that could cause external leakage.

An initial survey is always made whenever there is a new experimental 
setup that is likely to cause a different leakage environment.   All 
new devices are surveyed upon initial installation.

Much of this is driven by state regs which usually require these 
survey frequencies.   For my major clients wheere I am the RSO, I 
have taken the most restrictive (if reasonable) requirements and 
developed a uniform policy.

> 
> How often do you survey electron microscopes?

> What other machines do you survey and how often?
> 
> Yearly?    More of less frequently?  If more or less, how often?
> 
> Under what other conditions do you survey the machines?
> 
> Post maintenance?  New experimental set up? What other conditions?
