Phosphorus-32 (32P) is a radioactive isotope of phosphorus. The nucleus of phosphorus-32 contains 15 protons and 17 neutrons, one more neutron than the most common isotope of phosphorus, phosphorus-31. Phosphorus-32 only exists in small quantities on Earth as it has a short half-life of 14 days and so decays rapidly. Phosphorus is found in many organic molecules and so phosphorus-32 has many applications in medicine, biochemistry, and molecular biology where it can be used to trace phosphorylated molecules (for example, in elucidating metabolic pathways) and radioactively label DNA.

  • Fosfor-32 ( 32 P), neboli také radiofosfor, je radioaktivní izotop prvku fosforu, vyzařující záření beta. Jeden jeho atom obsahuje 17 neutronů a 15 protonů, což je o jeden neutron více než v nejběžnější formě fosforu – ve fosforu-31. Fosfor-32 je na Zemi pouze v malém množství, navíc má krátký poločas rozpadu (14,3 dní), takže se rychle rozkládá. Fosfor-32 se využívá v odvětvích jako je lékařství, biochemie a molekulární biologie. (cs)

  • Fosfor-32 of 32P is een radioactieve isotoop van fosfor. De isotoop komt van nature niet op Aarde voor. Fosfor-32 ontstaat onder meer bij het radioactief verval van silicium-32. (nl)
  • 磷-32 (32P)是一种磷的放射性同位素。磷-32核子含有15个质子和17个中子,比磷-31(磷的天然同位素)多一颗中子。磷-32的半衰期为14.29日。 磷出现在很多有机化合物里,所以磷-32在核医学里可以做放射性追踪剂和被标记的DNA。 (zh)
