Radiation Dosimetry
Radiation dosimetry is worn to monitor radiation levels. It should be worn when required by your
regulatory jurisdiction, company safety policy, or RSO. Typically several rounds of dosimetry are used,
along with exposure time and use estimates to determine whether dosimetry should be discontinued. If
no dosimetry is used, a written justification must be kept on file.
Dosimetry can be obtained for companies such as:
Radiation Detection Company
3527 Snead Drive
Georgetown, TX 78626
Landauer Corporate Office
2 Science Road
Glenwood, IL 60425-1586
Dosimeters can be worn on a finger with a ring badge or on the body using a whole-body badge. Your
organization should have an established dosimetry program to determine the required use and type of
dosimeters. Always follow the instructions provided by the vendor when using dosimetry badges.
Dosimeters should be returned to the vendor for analysis.
Dosimetry badges are changed on either a monthly or quarterly basis. The correct option depends on the
dose received. If dosimetry is used, most users require a quarterly change – but this also depends on
whether the user is receiving a dose from another source.
Electronic dosimeters can also be used to electronically display the dose. Electronic devices are sold by
companies such as:
Canberra Industries, Inc.
800 Research Parkway
Meriden, CT 06450
Whatever method you select, be sure to maintain the proper records as mandated by your local
regulatory agency. Be sure to check for the time required in your juristiction. Some regulators require that
records are kept until the license is terminated, and then transferred to the regulatory agency.
