The open window allows all types of radiation through, therefore showing exposure to Beta and Gamma radiations. Windows 2 and 3 are plastic of different thicknesses allowing the person examining the film to tell what kinds of Beta radiation they have been exposed to. Windows 4,5 and 6 are of different metals including lead and tin allowing the detection of gamma rays and other ionising radiations. The final exposure of the film will show how much and what kind of radiation the worker has been exposed to.

How can a film badge show the type and level of radiation exposure? Photographic film. Debla Teoh Explainer. What unit does a Geiger counter measure?
Geiger counters that have meter readouts in CPM, that is, Counts or Clicks per Minute , mimic the audible clicks in visual form. CPM is the unit normally used to measure Alpha and Beta radiation.
Eliodoro Jiboedov Pundit. What are dosimeters made of? A radiation dosimeter is a scientific instrument used to measure exposure to ionizing radiation. Commonly worn in the form of a badge or bracelet, these meters contain phosphor crystals capable of trapping electrons freed by harmful ionizing radiation.
Aneliya Trinidad Pundit. What is the purpose of personal dosimetry? Personal dosimetry is used primarily but not exclusively to determine doses to individuals who are exposed to radiation related to their work activities.
Personal Dosimeter. Radiation dosimetry is the measurement, calculation and assessment of the absorbed doses and assigning those doses to individuals. Danielly Comella Pundit. How much does a dosimeter cost? You can see examples of the pencil dosimeter and charger at various vendor sites.
Joaozinho Passarada Pundit. How often should a dosimeter badge be turned in? Dosimeters are issued every three months. Return all used badges for processing as quickly as possible. If a badge has not been worn or used by a participant for that monitoring period, please note that fact on the rotation record.
Dose to the lens of the eyes is due to an intermediate range of radiations and energies and is applied against the lens of the eye dose limit. In the case of ring badges, dose is only reported as shallow dose and is applied against the extremities dose limit.
Doses are reported in millirems. The minimum reported dose for x-rays for body badges is 10 millirems for x-rays, and for ring badges is 20 millirems.
If no dose is reported, the total dose received was less than the minimum reported dose. Contact EHS for a copy of your radiation exposure history. EHS maintains radiation exposure records indefinitely. If you terminate employment with the University, EHS will provide your radiation exposure history to you or your new employer upon request. Do not take Princeton monitoring badges to any other institution. Princeton University provides badges to you solely to measure the radiation dose you receive while working at Princeton University.
If you perform radiation work at another institution, it is the responsibility of that institution to provide you with monitoring badges. However, Princeton University must still control the dose you receive while working at Princeton so that your total occupational dose does not exceed regulatory dose limits.
