Scope note: Partículas elementales de vida corta presentes en la radiación cósmica o generadas a partir de la desintegración nuclear. Su masa se encuentra entre la de los protones y la de los electrones, y pueden tener carga positiva, negativa o neutra. Los mesones pi (piones) son más pesados que los mesones mu (muones) y se han propuesto para radioterapia anticancerosa dado que su captura y desintegración por la materia produce una radiación secundaria potente pero de vida corta.

Scope note: Short-lived elementary particles found in cosmic radiation or produced from nuclear disintegration. Their mass is between that of protons and electrons and they can be negative, positive, or neutral. pi-Mesons (pions) are heavier than mu-mesons (muons) and are proposed for cancer radiotherapy because their capture and disintegration by matter produces powerful, but short-lived, secondary radiation.
