In the detection of irradiated food,Photoluminescence method(abbreviated as PSL method, EU standard number EN13751) andThermoluminescence methodTL (abbreviated as TL, EU standard number EN1788) are the two most widely used methods and can be applied to the vast majority of common foods and drugs.

PSLIn the method, for low sensitivity samples, it is necessary to performirradiationRe check and confirm after processing; In the TL method, each sample detection requires the sample to be testedirradiationPerform secondary luminescence curve measurement afterwards. Therefore, regardless of the TL method or PSL method, the irradiation device is an indispensable equipment for correct detection. Natural radioactive sources pose great danger and are strictly controlled in practical use. The X-ray irradiation device only produces X-rays when powered on and subjected to high voltage. Once the power or high voltage is turned off, the radiation will terminate. Moreover, the intensity and duration of radiation can be manually set or controlled, making X-ray irradiation devices an ideal alternative to natural radiation sources for radiation detection.

Although ordinary X-ray machines can also irradiate samples in principle, the vast majority of them are designed for use in the medical or biological fields. Ordinary X-ray machines are usually bulky and heavy, making transportation and movement very inconvenient; And the radiation intensity is very high, requiring strict protection. In addition, ordinary X-ray machines are also relatively expensive, especially imported equipment, which can cost millions of yuan. These factors severely limit the use of ordinary X-ray machines in radiation testing laboratories. For this purpose, we have developed a specialized X-ray irradiator for laboratory irradiation testing - the XR1375 miniature X-ray irradiator, specifically designed for irradiation treatment of small samples in TL and PSL methods, filling the gap in this field both domestically and internationally.

XR1375The miniature X-ray irradiator mainly consists of three units:high-voltage generator、Sample irradiation roomreachsoftwareThe high-voltage generator is used to generate X-rays, and the irradiation chamber is where the sample is irradiated. The irradiation parameters can be set in the software. The system has strict protection against radiation, and there is no trace of radiation leakage even near the chassis; And there is a linkage protection mechanism between the sample chamber and the high-voltage generator. Once the drawer of the sample chamber is opened, the high voltage will be immediately cut off, ensuring safety during use. The XR1375 miniature X-ray irradiator is small in size and lightweight, and can be placed on laboratory countertops.
