Foreword
This standard is identical with IEC 60325.2002 "Radiation protection instrumentation α, β and α/β (β energy > 60keV) contamination meters and monitoring
Instrument "(in English).
For ease of use, the standard of IEC 60325.2002 made the following editorial changes.
--- Delete foreword international standards;
--- "2 Normative references" by adopting international standards of international standard in place of the standard corresponding to GB/T 4960.6
Instead of IEC 60050 (393).1996 and IEC 60050 (394).1995, deleting the standard in the text does not appear;
--- Deleting 10.3.1 and 10.3.1.1.1 regarding the AC does not meet the conditions of the content;
--- According to Chinese customs for some formatting has been modified (for example. Note plus behind ".", followed by a series Item Description will be. ""
To ";";
--- Use the decimal symbol instead of the international standard decimal symbol ",". ",";
--- 6.8 has been specified since the content "mechanical impact", so deleting "11.2 mechanical impact," while deleting "11.1 Overview";
--- Table 3 "β radiation" a column "3.7MBq" and 9.6.3 paragraph 2 "370kBq" match instead 370kBq;
--- Table 3 "warm-up time (portable instrument)" the last line of a column, "8.7.2" and the text does not match the standard (8.7.2 is the body of the
Standard Test Method for overload protection) to "8.5.2";
--- Table 3 "Power" column in the frequency of "+ 1Hz -3Hz" to "47Hz 51Hz", and standard text 10.3.1.1.3
Representation agreement;
--- Table 3 "radiation emission" column of the "1V/m" and 10.4.6.1 of "0.1V/m" does not match to 0.1V/m.
This standard replaces GB/T 5202-1985 "α, β, and α-β surface contamination meters and monitors."
The main changes compared to 5202-1985 standard and GB/T as follows.
a) the standard name to "Radiation protection instrumentation α, β and α/β (β energy greater than 60keV) contamination meters and monitors";
b) increase the "instrument is classified" chapter;
c) In the "environmental impact" chapter added "electromagnetic compatibility" content, including the "electrostatic discharge", "radio frequency electromagnetic fields," "by the pulse
Group and conducted disturbances induced by radio frequency "," surge "," voltage sags and short interruptions "and" radiation emission requirements and test methods "drop.
The standard proposed by China National Nuclear Corporation.
This standard by the National Standardization Technical Committee on nuclear instrumentation.
This standard was drafted. Shenzhen Academy of Metrology and Quality Inspection, Xi'an Nuclear Instrument Factory Nuclear Group.
The main drafters of this standard. name Lee Siu, Shen loyalty, Zhou Yingchun, Liangping.
This standard was first released in July 1985.
GB/T 5202-2008/IEC 60325.2002
Radiation protection instrumentation α, β, and
Contamination meters and monitors
1 Scope
This standard applies to the direct measurement or detection of direct emission α and/or surface contamination meters and monitors β nuclides, which includes at least.
--- Detecting means (including the counter, scintillation detector or a semiconductor detector, etc.), it can be fixed or connected by a flexible cable connection, or
Who constitute a separate device;
--- Measuring device.
Some gauges and monitors the detection devices and measuring device composed in the detection and the instrument can separate case, alone
With a detection device. To meet this standard, including all the requirements of detection devices and measuring devices instrument complies with the requirements of this standard, or detection device
And measuring devices conform to the relevant part of the requirements of this standard.
NOTE. For the latter use proven compliance with this standard, but can not infer portfolio allocation other special equipment is also standard. After a
Ways it can use to allow users to use different combinations of factory production device configuration.
This standard applies to.
--- Α surface contamination measuring instrument;
--- Α of surface contamination monitors;
--- Β surface contamination meter;
--- Β surface contamination monitors;
--- Α/β surface contamination meter;
--- Α/β surface contamination monitors.
After two devices can simultaneously determine α and β contamination, and the measurement results are shown.
--- Α (β, α/β) surface contamination measuring instrument. includes one or more radiation detectors and related devices or basic functional unit. Check in
When the surface contamination, for measuring α (β, α/β) surface emissivity;
--- Α (β, α/β) of surface contamination monitors.
This standard also applies to those who have special-purpose equipment and special nature of the surface of the measurement instruments designed. But some of the required standard
Need to be amended or supplemented in accordance with the special requirements of these instruments.
If the instrument can achieve a variety of functions, the instrument must meet all of these requirements with different functions. If the instrument in a function
Lord, both other functions, the instrument must meet all the requirements of the main functions, and as far as possible to meet the requirements of other functions.
This standard does not apply to the measurement or detection of maximum energy less than the radiation monitor or meter 60keVβ particles.
The purpose of this standard is to provide standards and give some examples of suitable methods, also provides general characteristics, general test conditions and parties
Certificate, radiation characteristics, electrical safety, environmental characteristics, and α, β and α/β contamination meters and monitors.
