Radioactive, английский
- Radioactive can generally describe the property of a substance (or more accurately atomic nuclei) which are unstable and spontaneously decay (disintegrate) with the release of energy, the energy being either electromagnetic radiation , particulate or both
- Радиоактивный
- Generally, the property possessed by certain elements, such as uranium minerals, of spontaneously emitting alpha, teta, and/or gamma rays by the disintegration of the nuclei of their atoms.
- Atoms that are energetically unstable and decay to a stable condition by emitting radiation are said to be radioactive.

Magnetic particle inspection (mt), английский
A method for detecting discontinuities on or near the surface in suitably magnetized materials, which employ finely divided magnetic particles that tend to congregate in regions of the magnetic non-uniformity, i.e., along cracks, over inclusions, voids, etc.
Computed tomography (rt), английский
A method by which a radiograph of a predetermined interior plane of a thick material is obtained through the use of a computer. the images resulting from a series of exposures at different angles are stored and reconstructed into a single image by the computer.
