This standard is the first industry standard for entry-exit inspection and quarantine.
Import and export granite spot radioactive dose
Detection control standard
1 Scope
This standard specifies the detection method of gamma ray dose on the surface of imported and exported granite, the determination of test results and the equivalent dose rate exceeds the test.
Management values for the disposal of granite.
This standard is applicable to the detection of γ-ray dose at the site of import and export granite blocks. On-site gamma ray dose detection for other stone materials can be referred to
carried out.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
The import and export granite inspection lot for delivery inspection shall be the same contract, the same invoice, the same origin and product name, and the same receiving unit or department.
The door and the granite shipped by the same means of transport.
3.2
Some nuclides spontaneously emit particles or gamma rays, or emit X-rays after orbital electron capture, or spontaneous cracking
The changing nature is called radioactivity.
3.3
Radiation structure of natural radioactive materials by cosmic rays and natural distribution (in the surface, in the atmosphere, food, water, etc.)
Ionizing radiation.
3.4
At the inspection site, the natural environment background radiation measured by the same instrument under the same environmental conditions is not affected by the object under test.
3.5
The equivalent dose at a point is the product of the absorbed dose (D) and the radiation weighting factor (WR), denoted as H. Its international unit is. Sivot
(Sv), 1Sv = 1 J/kg.
3.6
The equivalent dose per unit time is called the equivalent dose rate. Its international unit is. Swarth/sec (Sv/s). Practical unit. Wei Xiwo
