This part is Part 6 of GB/T 27476.

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

Introduction

The safe operation of testing laboratories may involve dangerous factors such as electrical, mechanical, non-ionizing radiation, ionizing radiation, chemistry, and microorganisms.

GB/T 27476 is a series of safety standards for testing laboratories formulated for these risk factors, which aims to improve the safety management of testing laboratories.

Management ability and safety technology ability, reduce the safety risk of testing laboratory operation.

GB/T 27476 is a series of safety standards applicable to testing laboratories, which are in common with the safety standards of laboratories in professional fields that have been promulgated. To form a safety standard system for testing laboratories.

This part is intended to prevent workers from unnecessary exposure to radiation when using ionizing radiation sources in the laboratory and other personnel may be accidentally or Expected accidents involving ionizing radiation injuries. At the same time, the important characteristics, harmfulness and other basic radiation of radioactive materials and irradiation devices are described Protection information. Testing laboratory safety Part 6: Ionizing radiation factors
