DEFINITION

Classification: 264/473

High energy or particulate radiation (e.g., X-ray, gamma ray, neutron, etc.):

(under subclass 464) Processes wherein the directly applied energy is irradiation with high energy electromagnetic radiation or high energy particles.

(1) Note. The term high energy electromagnetic radiation or high energy particles, as employed here, includes X-rays, gamma rays, and particulate energy (i.e., charged particles and atomic emissions such as alpha rays, beta rays, and neutrons). Electromagnetic wave energy measured below wavelengths of 100 Angstroms (10 to the minus 8 meters) will be considered high energy electromagnetic radiation or high energy particle radiation. This subject matter is often referred to as high energy ionizing radiation.
