• According to the relevant national laws and regulations, the irradiation device must be checked and accepted by the competent department before it is officially put into operation, and obtain the "radiation device safety license", "radiation processing measurement license" and "radiation processing health license". The safety protection facilities of irradiation devices must conform to national standards. The dosimeter must meet the requirements of the national measurement and testing regulations, and determine each verification item according to the regulations.

  • An irradiation mode should be established according to the conditions of the irradiation device and the irradiation product. The principle is to maximize the use of the irradiation space under the condition that the dose unevenness in the product meets the requirements.

  • For static irradiation, an equal dose curve should be drawn to select the position and method of product stacking and the procedure of inversion. The dose distribution of simulated products with different densities is measured to verify whether the total average dose and dose unevenness in the products meet the processing requirements under the above stacking mode.

  • For dynamic irradiation, the relationship between the pause time and the total average dose and unevenness of the product should be established when irradiating products with different packaging densities, and the scale coefficient and the position of the minimum and maximum dose in the product box should be determined as daily The dose monitoring point during processing

  • Before the irradiation device is put into use, a series of production management rules should be formulated, such as operation management rules, staff management system, safety management system, irradiation product quality management system, dose monitoring system, request report and countermeasures for failure, laboratory management system, environmental monitoring system, financial management system, file system, workshop production management system, visit reception system, etc.
