Dosimeters Part Two

back arrow       forward arrow

Nurses on wards where radiation patients are treated are  issued Luxel dosimeters only.  Nurses on other floors that care exclusively for patients with permanent implants do not receive dosimeters. This is because any dose received would be far below regulatory monitoring requirements.

Visitors will not be given dosimeters since their exposure is limited through the procedures outlined in this manual.

Dose results are sent to each area monthly and are also available from Radiation Safety at any time upon request.

What are my dose limits! (Additional information can be found in the University of Washington Radiation Safety Manual Section 6-5) .
