Instructions on Using Landauer’s Dosimetry Service

Your Shipment

Your badges will arrive in a shipping container with a packing list/service change order form and at least one control dosimeter. Personal identification, including account number, participant number and beginning wear date is printed on film badges and laser etched on TLD rings and body badges.

Returning Used Dosimeters

• About 5-8 days before the beginning of a new wear date you will receive a new shipment of dosimeters. Please store these in a radiation-free area until the first day of the new wear period. On the first day of the new wear period change the dosimeters over. For film badges put the new inserts into the holders and remove the used inserts to return to Landauer using the return box or the return label. PLEASE RETAIN YOUR FILM BADGE HOLDERS; DO NOT RETURN WITH THE USED DOSIMETERS. It is important that the inserts are loaded correctly into their holders (see sheet on loading film badges).

Unused Dosimeters

• If you wish a dosimeter to be reported as unused, please list the dosimeters that have not been worn or otherwise used (state badge type, part number and name), and include the list with the return shipment. It is important that you have an authorised person verify that the dosimeters are unused and sign the list accordingly.

Contaminated Dosimeters

• If you suspect that a dosimeter has been radioactively contaminated DO NOT RETURN it to Landauer. Instead, an estimated dose should be sent to us by your Radiation Protection Adviser.
