Dosimeters are used to record any exposure to radiation, but they are not able to detect the small amounts of radioactive material used in a university environment. Similarly, if this material is introduced into the body, these internal doses will not be recorded. A dosimetric tag is used to control radiation, but it does not provide any protection against radiation. The purpose of dosimetry is to record the occupational radiation that people in the medical field, for example, are exposed to on a daily basis.
The measurements recorded on the film are compared to the annual cut limits and the ALARA levels. It is important to remember to return the dosimetry plate when leaving the workplace, as this will ensure accurate exposure readings. Dosimetry badges are used in a variety of industries and are an essential tool for monitoring employee health. In conclusion, dosimetry badges are an invaluable monitoring tool and should be treated with respect.
They do not protect or shield anyone from radiation exposure; they simply report the amount of radiation (if any) that the user has been exposed to. Many professionals wear their dosimetry badge religiously, as it helps them monitor their organs and ensure they are safe in their field of work. Pocket dosimeters, or electronic personal dosimeters, should be reviewed every 12 months to determine the correct response to radiation, and records must be kept in accordance with § 34,83. If a personnel dosimeter is lost or damaged, the worker must stop working immediately until a replacement personnel dosimeter is provided that meets the requirements of paragraph (a) and exposure is calculated for the period of time from issuance to loss or damage of the personnel dosimeter. Radiation dosimetry is a calculation of the dose absorbed into tissue that results from exposure to ionizing radiation. Personnel dosimetry is necessary when a person's radiation exposure is likely to exceed 10% of the dose limit, when a new activity is initiated, or when there is no other method that can properly determine a dose in an accident situation.
It is also important to make sure that the dosimetry badge is worn correctly so that readings can be captured accurately. Film plates should be changed at least once a month and all other personnel dosimeters that need replacing should be replaced at least quarterly. If the dosimeter is placed under an apron, it will be protected and will not record any dose on exposed parts of the body.
