Re: Dose Rates from Patients -Reply

["Wesley M. Dunn" <WDUNN@brc1.tdh.state.tx.us>]

To remove Barbara's regulatory rachet (well, ok, so only in Texas),
we have revised our regulatations for this particular instance
(actually, the original impetus was due to conventional brachytherapy
patients).

Texas Regulations for Control of Radiation (TRCR) 21.502(b)
exempts healthcare personnel from badging in high radiation areas IFF
they are not likely receive >10% of the external limit AND they
have an active ALARA program.

As pointed out earlier, the doses from these cases tend to be very
low as long as staff are appropriately trained.
