Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses the translation method identical with IEC 62438. Mobile 2010 "Radiation protection instruments to measure the photon and neutron radiation environment of Instruments. " Consistency correspondence with international standards in this standard references of the following documents.

1 Scope

This standard applies to mobile radiation detection system, which is used to detect, identify and quantify environmental photons and (or) neutron emission Body, including the location and distribution of the radiation source.

The purpose of this standard are.

- establishing a definition;

- minimum requirements specified instruments;

- predetermined configuration and operation requirements;

- given test and calibration methods;

- provide guidance for the procurement of suitable equipment.

Typically, the mobile instrument systems for nuclear radiation environment measured by the detector, the detector signal processor, position sensors, with Data recorded on the vehicle, the operator monitoring and real-time display/alarm capability. In addition, the advanced systems through remote sensing technology can be several According to the streaming operations center.
