Explore gamma rays. Learn the definition of a gamma ray and see its characteristics. Find the sources of gamma rays on Earth and outer space, and...
The method utilising a portable gamma-ray source and a Geiger-Mueller counter has been applied in laboratory conditions for determinations of gamma-ray absorption coefficient in wood of several deciduous softwood species. Results might be of importance in characterising the wood tissue and also in ...
Basically, an X-ray machine transmits the radiation through the body. Some of it comes out on the other side of the body (where it is exposed to a digital detector to form an image) while some of the radiation is absorbed in body tissues (which is referred to as ‘radiation dose’ a...
Renders a complex scene with reflective surfaces using the new ray tracing extensions. Shows how to do recursion inside of the ray tracing shaders for implementing real time reflections. Callable shaders can be dynamically invoked from within other ray tracing shaders to execute different shaders ...
Health Physicists can use the gamma ray images as a fundamental part of an overall dose reduction strategy. This application note illustrate how the system can be used in a multitude of ap- plications i 传感器头的遥控操作在高辐射环境里允许伽马射线图象的安全承购。 健康物理学家能使用伽马射线图象...
Radiation is the release of energy, whether it takes the form of waves or particles. Radioactivity refers to the decay or splitting of an atomic nucleus. A radioactive material releases radiation when it decays. Examples of decay include alpha decay, beta decay, gamma decay, neutron release, ...

Radiation from the higher-energy end of the ultraviolet spectrum, in addition to X-rays and gamma rays, is known as ionizing radiation: It is energetic enough to be able to knock electrons off of atoms, turning the atoms into ions. Ionizing radiation can damage DNA and cause a multitude of...
