Area dosimeters are calibrated in equivalent personal superficialHP(0.07) and deep HP(10) dose, with the same configuration as the whole body dosimeter and follow the same process of the same.

Basic rules of use:

  • They must be placed at a specific point defined by the installation RP manager every month, which is representative of the personnel dose to be controlled with this dosimeter.

To make the estimation of equivalent personal dose from area dosimeters, an additional calculation is required which takes into account the measurements on the representative points of the area where the workers are, the time spent there and the radiological workload.

This kind of measurement is useful where estimated doses are zero or below the detection level of 0.10mSv/months. When the doses measured in the area are significative, the calculation and associated recordings are generally more expensive than the use of individual personal dosimeters.
