Introduction

Radon is a radioactive trace gases, the earth's crust are radioactive series of natural radionuclides 238U, 235U and 232Th daughter of 226Ra, 223Ra And 224Ra decay produced. Isotopes of radon (222Rn, 219Rn and 220Rn) by three decay chain decay, and finally terminates in the stable lead with Isotope. Isotopes of radon and thoron 220Rn commonly referred to as 1). Note. Under normal circumstances, due to the very short half-life of 219Rn, compared with the two other series of radon activity, its activity and decay daughters (RnDP2)) activity Can be ignored, its health effects are not important. Therefore, in this part of 219Rn and its decay daughters is not considered. Radon decay of short-lived isotopes and their respective daughters (RnDP) (for example, 222Rn of 218Po, 214Pb, 214Bi, 214Po, 220Rn of 216Po, 212Pb, 212Bi, 212Po, 208Tl) is very important, as they form public and occupational radiation exposure of staff to accept the natural home To section. In some people the workplace (for example, underground mine, mineral water and waterworks) work by a very significant level of radon Exposure. Radon is a gas and its isotopes and their daughter are fine particles of these different amounts of airborne radionuclides are present in the form. High accuracy Measurement of natural radioactivity in the atmosphere of this level for health physics is valuable. Since these radioactive elements in the air and in phase The measuring instrument should have unique behavioral characteristics, it is necessary to test methods for measuring instruments such norms. GB/T 13163 series of standards, including radon and radon testing and calibration of measuring instruments special requirements in order to facilitate application, GB/T 13163 Series of standards are divided into the following different parts. GB/T 13163.1 (normative). This section relates specializes in radon and radon (RnDP) The term measurements with the unit, briefly RnDP for radon measurement and test equipment and calibration of radon test system (STAR). GB/T 13163.2 (normative). This section is dedicated to 222Rn and 220Rn meter test. GB/T 13163.3 (normative). This section is dedicated to the 222Rn and 220Rn daughters (RnDP222 and RnDP220) meter test. GB/T 13163.4 (normative). This section details the structure and application of the STAR test. GB/T 13163.5 (informative). This part is about the characteristics of radon and its daughters and technical guidelines of the measure. 1) This section does not use the term thoron, radon represents nuclides 220Rn and 222Rn. Especially when a particular radionuclide, marked its chemical symbol and mass number. 2) RnDP is an acronym for radon decay products, sometimes represented by radon daughters. Radon decay products or its abbreviation RnDP refers to this section concern radon decay All short-lived progeny. For a particular daughter isotopes in the upper left corner plus the quality of its chemical symbol numbers. Symbol RnDP plus right The subscript numbers (222,220) refers to the corresponding isotopes of radon daughters all. (For example, RnDP222 means of 222Rn daughters 218Po, 214Pb, 214Bi, 214Po, RnDP220 means of 220Rn daughters 216Po, 212Pb, 212Bi, 212Po, 208Tl).

1 Scope

GB/T 13163 provisions of this part of the measure outdoor, residential and workplace (including underground mines) in the air carrier's short-lived radon daughters Product activity and/or special environmental requirements α potential concentration of the instrument. This section applies to crawl based on sampling, continuous sampling measurement technology and electronic integration of almost all types of electronic equipment. Correct Activity measurement sampling means (such as filters) can be performed on or after sampling during the sampling period is completed. GB/T 13163.1-2009 laid down in the various types of instruments used to measure.
