Re: Individual monitoring device question.

["Robert Denne" <rdenne@worldnet.att.net>]

Please remember, whole body is defined by the NRC as elbows-in, ankles-up.
This includes the head.  The dosimeter must be worn to reflect the dose to
the whole body.  If beta is also a concern and the dosimeter reads a beta
component, having the dosimetry under the apron ain't gonna cut it.

I believe Illinois is an agreement state?
