All licensed radioactive material users are required by law to maintain accurate dosimetry records. Dosimetry records are required to reflect individual exposures of anyone exposed to the radioactive materials in their possession including but not limited to their workers, contractors, visitors, etc.
One highly cost-effective means of recording doses are TLD (thermo luminescent dosimeter) badges which are passive devices worn by users that accurately capture the radiation dose. The badges are sent to a NVLAP accredited laboratory every three months where they are processed in a highly controlled manner to read the total accumulated dose of each badge. An Occupational Radiation Exposure Report is then generated showing the individual doses for all badge wearers.
While it may be possible to avoid use of badges by calculating individual exposures, most concur that passive measuring devices like the TLD offer superior record keeping given the innumerable circumstances, variabilities, and unforeseen situations that may not have been considered or captured by calculations alone.
Due to the high accuracy and rigorous NVLAP accreditation TLD programs incur, TLDs are widely recognized as legal records of dose. In the event a current or past employee attempts to legally blame their cancer on your company, your only saving grace will be accurate and thorough dosimetry records. Protection against such action is acquired by either hiring an expensive Certified Health Physicist to setup a program that must be rigorously followed without deviation, or purchasing an inexpensive dosimetry badge service that automatically provides legally certified and verifiable records for you. The choice is yours.
Qal-Tek helps make the choice a lot easier by offering a very low cost quarterly service using Mirion certified TLD dosimetry badges. Their certified badges and record keeping are proven, defensible, and ultimately offer you low cost protection for your employees and your company. It’s a win-win scenario.
