A separate dosimeter known as “control dosimeter” is included with each shipment free of charge. The control dosimeter(s) monitor background radiation in transit from and to LANDAUER® and storage.
The dose received by the control dosimeter is subtracted from the participants’ dosimeters. They should not be used for any other purpose.
Luxel+®, SATURN® and VISION® control dosimeters are clearly labelled «CONTROL».
SATURN® and VISION® control dosimeters are indicated by red body, yellow cap and “CONTROL” on the cap.
Store control dosimeters away from radiation, 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.
If you have any difficulty returning all of the dosimeters from the wear period in one shipment, LANDAUER can supply extra control dosimeters with your account at no extra charge.
Master control dosimeter
We can supply a master control dosimeter to replace multiple individual series controls, if all of your dosimeters are sent out and stored at a single location.
Series control dosimeter
If you store your dosimeters at different locations and have set up series for your account, we can supply control dosimeters to accompany each series.
