DEFINITION

Classification: 427/551

High energy electromagnetic radiation or high energy particles utilized (e.g., gamma ray, X-ray, atomic particle, i.e., alpha ray, beta ray, high energy electron, etc.):

(under subclass 532) Processes wherein the substrate prior to coating or the coated substrate is treated with high energy electromagnetic radiation or high energy particles.

(1) Note. The term "high energy electromagnetic radiation or high energy particles," as employed here and in indented subclasses includes; e.g., X-rays, gamma rays, atomic particles; i.e., alpha particles, beta particles, and high energy electrons. 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." This subject matter is often referred to as "high energy ionizing radiation." a. gamma ray ( .000 ---1.40 A); b. X-ray (0.1 ---100 A); c. atomic particle alpha ray; beta ray; d. high energy electrons accelerated. This list is not intended to be exhaustive and is not limited to the above examples.

(2) Note. Alpha rays are helium, and for classification purposes will not be considered as an ionized gas since, except in nuclear processes, they are not a naturally occurring ionization state under any normal earth conditions.
