Role of the control dosimeter

A separate dosimeter known as “control dosimeter” is included with each shipment free of charge. It monitors the background radiation both at the badge board locaton and during the transit from and to LANDAUER® laboratory to your facility.

The dose received by the control dosimeter is subtracted from the participants’ dosimeters. They should not be used for any other purpose.

What is a Control Dosimeter?

A control dosimeter is included with each shipment to monitor radiation received in transit or while stored in your facility. It is important to return this control dosimeter with that original shipment grouping for accurate analysis by the LANDAUER laboratory.

The control exposure is read and subtracted from each individual dosimeter in the shipment – separating the occupational dose from the background exposure.

Instructions for using control dosimeters

The control dosimeter(s) should be stored on the badge board. Store control dosimeters away from radiation (radioactive sources, X-ray rooms, other dosimeters), together with dosimeters not being worn, in a radiation-free location, i.e. normal background.

Control dosimeters MUST be returned with the dosimeters of the same wear period and from the same batch for which they were issued.

Do not wear and do not use the control dosimeter for any other purpose.
