This international standard applies to non-passive, direct reading personal dose equivalent meters and monitors used for measuring the personal dose equivalents Hp(10) and Hp(0,07) for X, gamma, neutron and beta radiations.
Establishments in some countries may wish to use this type of personal dose equivalent meter as the basis of a personal monitoring service approved for dose record-keeping purposes for radiation workers.
BS EN 61526 applies to personal dose equivalent meters with the following characteristics:
- They are worn on the trunk or the extremities of the body
- They measure the personal dose equivalents Hp (10) and Hp (0,07) from external X and gamma, neutron and beta radiations, and may measure the personal dose equivalent rates H& p (10) and H& p (0,07)
- They have a digital indication
- They may have alarm functions for the personal dose equivalents or personal dose equivalent rates.
This standard specifies requirements for the dosemeter and, if supplied, for its associated readout system. It also gives the general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and environmental characteristics.
