In order for the tests to be valid, they must be received within a certain time frame which varies depending on the type of test performed.
The return shipment of your dosimeters to the laboratory is an important step which is not to be neglected. Refer to the test user manual to find out how to ship your test to the lab.
You also have the option to purchase a prepaid, preaddressed shipping label. Please read the description before ordering and also to ensure that you have also selected the right one.
