However, inhalation or ingestion of alpha particles can be very dangerous. Once inside your body, alpha particles expose your tissues to radiation. Beta particles, on the other hand, are fast-moving electrons. They can travel and penetrate more than alpha particles. Beta particles can be stopped...
There are many different types of radiation detectors, from the widely used Geiger-Mueller probe (which is just a thin-walled cylinder filled with gas) to the high-purity germanium detector, which requires operation at the temperature of liquid nitrogen. Detectors can be used to simply indicate ...
When charged particles travel along a bent path with a velocity near the speed of light, as occurs in an electron synchrotron or a storage ring, an intense beam of light is emitted tangential to the path. This light has a smooth continuous energy distribution extending far into the vacuum ...
Beta particlesare electrons that move very quickly — that is, with a lot of energy. Beta particles travel several feet when emitted from a radioactive source, but they're blocked by most solid objects. Beta particles are about 8,000 times smaller than alpha particles — and that's what ...
摘要: PROBLEM TO BE SOLVED: To reinforce radiation control by freely and easily setting a travelling route, widening a measurement control range for it, achieving avoidance operation by considering safety for an obstacle on the running route, and minimizing required facility control....
(Mitteer et al.2015). In line with this, X-ray and γ-radiation requires high doses to elicit cell death. In contrast, particle and heavy ion radiation (emitting α and β particles) are densely ionising with high LET/RBE inducing markedly more DSB for the same radiation dose (Table1)...

Materials subjected to high dose irradiation by energetic particles often experience severe damage in the form of drastic increase of defect density, and significant degradation of their mechanical and physical properties. Extensive studies on radiation effects in materials in the past few decades show ...
