Phosphore isotope
Web- [Voiceover] Phosphorus-32 is radioactive and undergoes beta decay. So we talked about beta decay in the last video. Here's our beta particle, and the phosphorus is going to turn into sulfur. Let's say we started with four milligrams of phosphorus-32. And we wait 14.3 days, and we see how much of our phosphorus is left. WebNov 3, 2006 · The finding that the nuclear reaction P 32 →S 32 kills radioactive phage with an efficiency of about 0.086 per atom transformed presumably means that at least this fraction of the phosphorus atoms of the phage particle is situated in vital structures, and therefore that the vital structures contain nucleic acid.”

Phosphate oxygen isotopes (δ 18 O p) have been used to trace P sources. However, the application of this method has been greatly restricted due to δ 18 O P values from the potential source having wide and overlapping ranges.
