GB/T 29788-2013Radiation protection instrumentation -- Portable photon contamination meters and monitors (English PDF)

Foreword

Accordance with the standards GB/T 1.1-2009. Drafting Rules "Standardization Guide Part 1 standard structure and preparation of" given.

This standard uses the translation method identical with IEC 62363:2008 "Radiation protection instrumentation - Portable photon surface contamination meter and monitoring instrument".

Consistency correspondence with international standards in this standard references of the following documents.

1 Scope

This standard applies to the direct measurement or detection directly caused by the emitted photon radiation nuclides surface contamination of portable and mobile pollution test Meter and monitor, which includes at least.

--- Detection device (counter, scintillation detector or a semiconductor detector, etc.), they can use a rigid connection or cable connection or group Into a single device;

--- Measuring device.

This standard applies to.

--- Photon surface contamination measuring instrument;

--- Photon surface contamination monitors.

This standard applies to the measurement of photons emitted energy exceeding 5keV nuclides pollution detection device. This standard is used to evaluate that particular these objects are not proof performance of the device emitted photon surface contamination by radionuclides.

This standard also applies to those with special-purpose instrumentation and provides limited spectral information for the user specially designed instruments.

Note. These detection means may be used to measure photon radiation while producing alpha and beta radiation nuclides produced, in this case, according to the type of contamination shield alpha and beta radiation. Strictly speaking, if the shield, contamination occurs in the vicinity of the object being monitored, rather than on its surface.

The purpose of this standard is to provide standards and give some examples of suitable methods, also provides for photon contamination meters and monitors General characteristics, general test conditions, radiation characteristics, electrical safety, environmental characteristics and certificate requirements.
