1 giorno fa · Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
9 mag 2024 · radioactivity, property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously. It is, in essence, an attribute of individual atomic nuclei. An unstable nucleus will decompose spontaneously, or decay, into a more stable configuration but will do so only in a few specific ways by emitting certain ...

1 giorno fa · “These radioactive sources are imported and exported daily, and the maintenance of a high level of safety and security is essential as these radioactive sources may pose a risk due to accidental radiation exposure, inappropriate use or malicious intent,” said Lydie Evrard, Deputy Director General and Head of the IAEA Department of Nuclear Safety and Security, at the opening of the meeting.
5 giorni fa · Radiation therapy or radiotherapy ( RT, RTx, or XRT) is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator.
3 giorni fa · It is one of only four radioactive elements (along with bismuth, protactinium and uranium) that occur in large enough quantities on Earth for a standard atomic weight to be determined. [2] Thorium nuclei are susceptible to alpha decay because the strong nuclear force cannot overcome the electromagnetic repulsion between their protons ...
