Tungsten alloy needle shield is an injection instrument used in medicine to monitor drug efficacy by isotope tracer method. It has high density, good hardness, which can bear weariness, corrosion-resistant. It has good screening ability to all kinds of ray, which provides people with protection from radiation.
Isotopic tracer method is a microanalysis method using radionuclides as tracers to mark the study objects. By using the nuclear physics properties of radioactive isotopes which give out characteristic rays continuously, the nuclear detector can be used to track its position, amount and transformation in the body or in the body at any time. Although stable isotopes do not release radiation, they can be measured by mass analysis instruments such as mass spectrometers, gas chromatographs, and nuclear magnetic resonance.
