Radiation Limits / Categories for NM and RadTherapy Techs-Reply

["Marissa Bartlett" <BartlettM@health.qld.gov.au>]

Hey,

FWIW - we're a Nuc Med department and not in a cancer hospital.  However, we do do quite a number of therapy patients:

>1 what are the typical annual doses that your NM techs and Radiation
> Therapists get?
Nuc Med techs get roughly 200 - 250microSv/year

>2 have any other clinics / hospitals designated their techs as ARWs
 >(or the equivalent in your country), even though their exposures
> are not at all likely to exceed the public limits?
anyone who is badged is regarded as a radiation worker and subject to the 20mSv/year limit.  people who get badged may include people who will never get a reading but who would otherwise worry and/or complain.

>3 how have other facilities handled the extremity dose question
> i.e. where ring TLDs are _not_ required, but the RSO has 'an idea'
> that the extremity dose may be being approached or exceeded?
our hot lab staff wear ring badges when dipensing therapy doses.  

>4 Do other countries have similar rules about extremity monitoring?
not here
