Web33 P is a beta-emitter (0.25 MeV) with a half-life of 25.4 days. It is used in life-science laboratories in applications in which lower energy beta emissions are advantageous such as DNA sequencing. 33 P can be used to label nucleotides. It is less energetic than 32 P, giving a better resolution.
