What is BS EN 61577-4-Equipment for the production of reference atmospheres about?
BS EN 61577 is a European standard on radiation protection instrumentation that discusses the radon and radon decay product measuring instruments to ensure protection against radiations.
BS EN 61577-4 is the fourth part of the BS EN 61577 series that covers the general features concerning test and calibration of radon and radon decay products measuring instruments.
BS EN 61577-4 is also intended to help define type tests, which must be conducted to qualify these instruments.
BS EN 61577-4 addresses only the instruments and associated methods for measuring isotopes 220 and 222 of radon and their subsequent short-lived decay products in gases.
BS EN 61577-4 concerns the System for Test Atmospheres with Radon (STAR) needed for testing, in a reference atmosphere, the instruments measuring radon and RnDP.
Note: The clauses that follow do neither claim to solve all the problems involved in the production of equipment for setting up reference atmospheres for radon and its decay products, nor to describe all the methods for doing so. They do however set out to be a guide enabling those faced with such problems to choose the best methods for adoption in full knowledge of the facts.
Who is BS EN 61577-4-Equipment for the production of reference atmospheres for?
BS EN 61577-4 on the equipment for the production of reference atmospheres is useful for:
- Radon isotopes and decay products (STAR) manufacturers
- Radon isotopes and decay products (STAR) designers
- Radon isotopes and decay products (STAR) test personnel
- Occupational health and safety departments
- Risk assessment authorities
- Quality assurance departments
Why should you use BS EN 61577-4-Equipment for the production of reference atmospheres?
Radon is a radioactive trace gas produced by the decay of 226Ra, 223Ra and 224Ra, respectively decay products of 238U, 235U and 232Th which are present in the earth's crust. By decay, radon isotopes (i.e., 222Rn, 219Rn, 220Rn) produce three decay chains, each ending in a stable lead isotope. The radon isotope 220Rn is called thoron1.
BS EN 61577-4 provides you with the general description of a STAR, characteristics of a STAR, RnDP analysis and control, analysis and control of climatic parameters, requirements for the reference atmosphere provided by STAR, calibration and traceability of measurement methods and instruments used in a STAR and much more.
The requirements and characteristics provided by BS EN 61577-4 assist in improving the performance of STAR and ensure protection against severe health issues due to radiation.
With obedience and compliance to BS EN 61577-4, you can enhance the efficacy of the equipment for the production of reference atmospheres and manufacture a standardized product.
