DEFINITION

Classification: 600/407

Detecting nuclear, electromagnetic, or ultrasonic radiation:

(under subclass 300) Subject matter including means for detecting (a) radiation in the form of energy or mass released from the nuclei of an atom, (b) radiation included in the entire electromagnetic spectrum, or (c) radiation which consists of a vibratory disturbance in the pressure and density of a fluid, or in the elastic strain in a solid, and which has a frequency higher than that detectable by the human ear.

(1) Note. Included hereunder is apparatus for detecting radiation of the designated types emanating from the body (e.g., radiation from radioactive material in the body, etc.) and radiation of the designated types directed against and either reflected from or passed through the body. This subclass also includes means for detecting changes produced in fields of radiation of the designated types which result from placement of the body therein.

(2) Note. Included hereunder is a device usable in conjunction with testing apparatus involving nuclear, electromagnetic, or ultrasonic radiation. For example, subclasses 656+ relate to flexible catheters used to inject into the body (a) a radio-opaque material so that an X-ray will reveal the contour of a passage or (b) a radioactive material so that a suitable means for detecting the material can be used to trace its course.

(3) Note. Included in this subclass are devices utilizing X-rays which are photons, extranuclear in their origin, arising from changes in orbital (or other) electron energy levels. See subclass 436, indented hereunder, for devices utilizing intranuclear rays, such as gamma rays, which are photons intranuclear in their origin, arising from nuclear decay processes.
