GB/T 31835-2015Pocket-type personal radiation devices (PRD) for detection and alarming of radioactive material (English PDF)

Foreword

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

This standard uses redrafted law revision adopted IEC 62401:2007 "Radiation protection instrumentation used to detect the illegal transport of radioactive material Personal radiation alarm device. " for ease of use, the standard of IEC 62401:2007 made the following technical and editorial changes.

--- Standard name changed to "for the detection and alarm of radioactive material personal pocket radiometer";

--- Deleting Introduction;

--- Increase in "2 Normative references" in GB/T 4835.1-2012 and IEC 61526:2010, with GB/T 4960.6-2008 instead of IEC 60050-393:2003 and IEC 60050-394:2007;

--- Increasing the term "pocket-sized personal radiation meter" "nuclear material" "radioactive material" "radioactive materials" in "3 Terms and definitions" and "Reference conditions" and its definition; the standard term in a logical order and re-order categories, the "reference device" to "Radiometer reference point", "false positives" in the "false positive rate" for the notes, delete the unused standard terminology, such as "amount the conventional true value "" means "" effective range "" read "" standard deviation, "" routine testing "" acceptance test "" variance "and so on;

--- 4.2.1 "radiometer overall size (not including clips, clamping device or external alarm) should not exceed the length of 200mm, width 100mm and a thickness of 50mm "words" radiometer overall size (not including clips, clamping device or external alarm) should not exceed Long 150mm, width 80mm and thickness of 30mm ";

--- Description column item 4.2.3 a) and b) to 4.2.3.1 and 4.2.3.2;

--- 5.2.3.1 and 5.2.3.2 column item description a) and b) to read 5.2.3.1.1,5.2.3.1.2 and 5.2.3.2.1,5.2.3.2.2;

--- 5.3.1.2 suspended following paragraph to 5.3.1.2.1 "Overview" column Item Description a) and b) to 5.3.1.2.2 and 5.3.1.2.3;

--- Delete the contents of 6.1;

--- Because references GB/T 4835.1-2012 and IEC 61526:2010 "1" and the reference to the two criteria Included in the "2 Normative references", so delete reference.

1 Scope

This standard specifies the alarm designed to detect radioactive materials and personal pocket radiometer (PRD), functional standards, to performance Sum test methods.

This standard applies to the body worn pocket-sized personal radiation meter. PRD for detecting and indicating through ionizing radiation (including photons and /or neutron) the presence and approximate magnitude, alert the user of the presence of radioactive sources was significantly higher than the local average background level, but not for providing agent Measurement equivalent rate.

This standard does not apply to GB/T 4835.1-2012, IEC 61526. performance relates to radiation protection instrumentation 2010.

When the PRD for other conditions not worn on the human body, its relevant neutron performance may be degraded.
