What is BS EN 62387-Passive dosimetry systems for monitoring photon and beta radiation about?
BS EN 62387 is a European standard on radiation protection instrumentation that discusses passive integrating dosimetry systems for the individual, workplace, and environment for monitoring photon and beta radiation to ensure radiation protection.
BS EN 62387 applies to all kinds of passive dosimetry systems that are used for measuring
- The personal dose equivalent Hp (10) (for whole-body dosimetry),
- The personal dose equivalent Hp (3) (for eye lens dosimetry),
- The personal dose equivalent Hp (0,07) (for both whole body and extremity dosimetry),
- The ambient dose equivalent H*(10) (for environmental dosimetry), or
- The directional dose equivalent H’ (0,07) (for environmental dosimetry)
BS EN 62387 also applies to dosimetry systems that measure external photon and/or beta radiation in the dose range between 0,01 mSv and 10 Sv and the energy ranges given in Table 1. All the energy values are mean energies concerning the prevailing dose quantity. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.
BS EN 62387 is intended to be applied to dosimetry systems that can evaluate doses in the required quantity and unit (Sv) from readout signals in any quantity and unit. The only correction that may be applied to the evaluated dose (indicated value) is the one resulting from natural background radiation using extra dosemeters.
Note1: BS EN 62387, “dose” means dose equivalent, unless otherwise stated.
Note2: For Hp (10) and H*(10) no beta radiation is considered. Reasons: 1) Hp (10) and H*(10) are conservative estimates for the effective dose which is not a suitable quantity for beta radiation. 2) No conversion coefficients are available in ICRU 56, ICRU 57, or ISO 6980-3.
Who is BS EN 62387-Passive dosimetry systems for monitoring photon and beta radiation for?
BS EN 62387 on passive dosimetry systems for monitoring photon and beta radiation is useful for:
- Dosimetry system manufacturers
- Dosimetry system test personnel
- Dosimetry system designers
- Occupational health and safety departments
Why should you use BS EN 62387-Passive dosimetry systems for monitoring photon and beta radiation?
Dosimetry is used extensively for radiation protection and is routinely applied to monitor occupational radiation workers. A dosimetry system consists of dosimeters, measurement instruments and their associated reference standards, and procedures for using the system.
BS EN 62387 provides you with test procedures, performance requirements, requirements for the design of dosimetry, software, data and interfaces of the dosimetry system, radiation performance requirements and tests (dosimetry system), and much more.
The test methods and procedures provided by BS EN 62387 assist you in improving the performance of the dosimetry systems and monitoring photon and beta radiation and ensuring protection against severe health issues due to radiation.
With obedience and compliance to BS EN 62387, you can enhance the efficacy of the dosimetry systems and manufacture a standardized product.
What is changed since the last update?
BS EN 62387:2016 supersedes IEC 62387-1:2007, which is withdrawn. BS EN 62387:2016 has made some technical changes compared to the previous edition IEC 62387-1:2007. These include:
- Extension of the photon energy range for dosemeters to measure Hp (0,07) from the old range of 8 keV to 250 keV to the new range of 8 keV to 10 MeV
- Addition of performance requirements for dosemeters to measure Hp (3) for both photon and beta radiation. Such dosemeters can be used to monitor the eye lens dose.
- Addition of performance requirements for dosemeters to measure H’ (0,07) for both photon and beta radiation
- Correction and clarification of several subsections to obtain a better applicability
- Alignment of IEC performance requirements on dosimetry systems for measuring personal dose equivalents with the recommendations on accuracy stated in ICRP Publication 75, General Principles for the Radiation Protection of Workers
