Personal dosimetry workplace determines the effective doses in order to evaluate the irradiation of the monitored workers. The effective dose is determined on the basis of the measured dose equivalents. The effective dose is defined as the summary of all equivalent doses (described as transmission of energy for a certain period of time) in all the body organs or tissues multiplied by the respective mass coefficient. The mass coefficient is the expression of the relation between the probability of casual radiation effects and the equivalent dose.
Personal dosimetry workplace determines the effective doses in order to evaluate the irradiation of the monitored employees. The effective dose is determined on the basis of the measured dose equivalents. The equivalent dose (dose equivalent) is given by the product of multiplying the absorbed dose and quality factor characterising the biological effect of the particular kind of ionizing radiation on the human body soft tissue.

Personal dosimetry workplace carries out measurements of the personal dose equivalent Hp(d) in the following depths of the soft human tissues:
Dosimeters are calibrated before their first use (initial calibration), when the monitoring period changes (e.g. quarter period instead one month monitoring period), or after expiration of the calibration period (subsequent calibration). At calibration, the calibration factor is specified for every dosimeter. This factor expresses the deviation of the measured value from the standard dose. All calibration factors are preserved in the database of the workplace. Personal dosimetry workplace disposes with standards manufactured by THERMO ELECTRON CORPORATION. The standards of the workplace are traceable to the standard of national institute of metrology. The following types of dosimeters are calibrated:
The database of the determined effective and equivalent doses is available on the web-site of Personal dosimetry workplace. The database will provide you with the following:
Personal dosimetry workplace offers for hire the following dosimetry cards and holders:
The prices for hiring are available in the currently valid price list.
The workplace provides the service of dosimeter resetting in case when the bearer of dosimeter changed, and the dosimeter was not used for a longer time (more than 2 months). The resetting should prevent the risk of transferring the residual radiation doses.
