People wearing lead garments should place the whole-body dosimeter at neck level, outside of any lead protection. Dosimeters should be used to better reflect the amount of radiation an employee receives. Badges are worn on the torso to accurately inform the amount of exposure received to the body. Doses given to organs are reported as deep doses, while doses delivered to the body that do not reach the organs are reported as shallow doses.
Doses delivered to the lens of the eye are reported as ocular doses. When choosing between a ring or wrist dosimeter, it's important to evaluate the type of work an employee is doing. Employees working in environments where they are likely to receive high exposure of their extremities should use a wrist ring or dosimeter. If a single radiation dosimeter badge is used while wearing a lead apron, applying a Webster 1 calculation will reduce the deep dose reported to the employee to 30% of the measured dose.
A Webster 2 calculation can also be used to calculate the armor obtained when using a lead apron using two dosimeters. Dosimeter badges are easy to use and can accurately report exposure received from all types of ionizing radiation that can cause external exposure. A dosimeter is a cheap form of insurance that ensures that an employee is not exposed to high exposures that could leave an employer liable for injuries. Dosimeter badge management doesn't have to be a time-consuming activity; with RDC, the whole process is simplified and simplified.
When used correctly, a dosimeter can provide valuable information to the radiation safety officer to help keep employees safe. A radiation dosimeter badge can provide peace of mind for employees working with radioactive materials to ensure that harmful radiation exposure does not occur. This dosimeter does not replace the requirement for a radiation dosimeter badge for the pregnant radiation worker. This phenomenon is called thermoluminescence and dosimeters using this principle are often referred to as TLDs (thermoluminescent dosimeters).
New dosimeters will be delivered to employees, while dosimeters from the previous range must be returned to the dosimetry provider for analysis. When you receive your dosimetry badges in the mail, you may wonder where you should place them and what protocol you should follow when wearing them above or below lead covers. Employees working with low-energy isotopes that may not be detected with a wrist dosimeter should consider a ring dosimeter that may be closer to the isotope to more accurately reflect the dose received. It is important that the dosimeter used for Webster 1 calculations is always carried outside the lead apron to accurately measure the surface and eye dose.
While a designated storage location should help prevent the loss of a plate, if an employee loses their dosimeter at any time during the reading period, they should immediately request a replacement badge.
