Personnel monitoring in the Islamic Republic of Iran is mainly carried out by the use of Film Badge which consists of a Fomma  Personnel Monitoring  flim carried in a RPRDS film Holder. The film holder is made of plastic material and has five different filters and an open window.

  Film badge is designed to measure over a specified period of time, the radiation dose received by a person who is occupationally exposed to radiation.

  Photographic film badge can be obtained from the Parsian Radiation Dosimetry Service (PRDS), that is approved by the National Radiation Protection Department (Regulatory Authority) to offer a personal monitoring service.

  Film badge is issued to an individual who is occupationally exposed to radiation. It is for their use only and must not be used by any other individual or for any other purpose. 

  A photographic film must be used once only for the duration of its issue period. At the end of that period it must be returned promptly to the PRDS for assessment of the radiation dose that it has recorded. A new photographic film badge dosemeter is issued for the next monitoring period (2months).
Records of the dose received by each occupationally exposed person who is issued with a personal monitoring device, must be kept by the employer as required by article 15 of the Radiation Protection Regulation 1369.
  Care must be taken with each personal monitoring device to ensure that it is not subjected to environmental conditions or mishandling which may affect its reading or damage the device. Factors that may cause adverse effects include mechanical impact and exposure to heat, chemicals or water.

Minimum Measurable Dose: 

It has been estimated that the monimum dose measureable with this system are 0.12±0.04 mSv for high energy x and gamma-rays and 0.06±0.03 mSv for the diagnostic x-ray ernergy range. 

Identification Number:

User identification numbers will be printed over the films by using an automatic press numbering machine.  The numbers will be visualized over developed films .  

Monitoring period: Two Months.

Exposure range monitored for X-AND GAMMA-KAYS:

  • around 0.040keV: 0.01mSv to 1000mSv
  • around 1MeV: 0.20mSv to 20000 mSv
