How often should a dosimeter badge be turned in?
Wear your badge every day while working. Place in a radiation-free area after working hours. Do not remove the badge from your workplace. Place the badge in the neck or chest area, facing the radiation source.
What are the types of dosimeters?
There are two general types: dosimeter badges, which are used to measure cumulative doses over periods of weeks or months, and pocket dosimeters, which are generally used for monitoring over a shorter term.
Who is required to wear dosimeters?
Radiation workers
Who needs a dosimeter? Radiation workers who operate x-ray machines, flouroscopy units, certain unsealed and sealed radioisotopes or are exposed to other sources of gamma or high energy beta radiation are generally required to wear one or more dosimeters.
What happens if I wash my dosimeter?
Never intentionally expose a dosimeter to liquids or heat, as damage and loss of dose information may result. Check lab coats before sending them to the laundry, as washing and drying may damage dosimeters.
What is inside a dosimeter?
Source: www.nde-ed.org. Film badges, film badge dosimeters, are small portable devices for monitoring cumulative radiation dose due to ionizing radiation. Principle of operation is similar as for X-ray pictures. The badge consists of two parts: photographic film, and a holder. The film is contained inside a badge.
Why do radiographers wear dosimeters?
Badge dosimeter – Traditionally, radiographers have worn film or Thermoluminescent Dosimeters (TLD) dosimeters to measure their cumulative radiation exposure so they can ensure they are not exceeding the occupational limit of 5,000 mrem per year of ionizing radiation.
How often should radiation badges be changed?
Badges must be exchanged at the required frequency, either monthly or quarterly. When you are first given your badge, you will be told how often to exchange it. Badges are exchanged during the 1st week of each month.
