Identification process of radiation protective clothing
Ray protective clothing is a protective tool that can be used in some chemical industries. It uses plug-in lead rubber plate to protect parts, rather than using lead rubber as a whole. It is light in weight, light to wear and convenient to move. The identification of radiation protection is very strict. Let's take a look at the identification process of radiation protection clothing:
1. Appearance quality inspection of radiation protective clothing: observe by visual method under the condition of normal natural light or 200lx light source.
2. Specification and size inspection of radiation protective clothing: use measuring tools with scale to lmm.
3. Physical performance test: tensile strength, elongation at break and deformation at break are tested respectively. Lead rubber shall be carried out according to gb528. Dumb-bell I-type sample was used, and the tensile speed was 50 mm/min. Lead plastic shall be carried out according to gb1040. Type II sample is adopted, and the test speed is 10 mm/min.
4. Hardness test of radiation protective clothing: Lead rubber shall be conducted according to GB531. Lead plastic shall be carried out according to gb2411.
5. Tear strength test: Lead rubber shall be carried out according to GB/t529. The right angle sample without cutting mouth is adopted, and the stretching speed is 50 mm/min.
6. Lead equivalent test: the standard lead sheet substitution method is adopted, and the measurement is carried out by the ionization chamber X-ray exposure tester. Radiation Protective clothing plays a very important role in protecting human body from radiation hazards. Therefore, when identifying radiation protective clothing, strict procedures must be followed, only qualified products can better block the harm of radiation to human body and play a better role in protection.
Protective effect and application value of stereoscopic radiation protection method in intervention. Methods: 174 patients were treated with X-ray radiation protection measures such as lead rubber curtain under the bed, movable lead glass protective screen hanging beside the bed, medical lead protective clothing, lead Protective Scarf, lead goggles and increasing distance during intervention, use RAD60S personal alarm agent measuring instrument to measure the X-ray radiation dose before and after protection of protective materials, and conduct statistical analysis. Results: lead glass protective screen, lead protective clothing and a increase of the distance can significantly reduce the X-ray radiation dose, which has significant protective significance; X-ray radiation dose is positively correlated with digital subtraction angiography time, with the increase of and Subtraction Imaging time, the X-ray radiation dose received by medical personnel and patients increased significantly. Conclusion: three-dimensional protection can effectively reduce the dose of X-ray radiation in intervention and protect the health of medical personnel and patients.
