Kegunaan isotop telurium
- 120Te is used for the production of 120gI, where “g” indicates ground state, via the 120Te (p, n) 120gI reaction, which is used as a positron emission tomography (PET) and beta-emitting isotope,. 120gI has a half-life of 1.36 h. 122Te is used in the production of the radioisotope 122I (with a half-life of 3.6 min) via the reaction 122Te (p, n) 122I, which is used in gamma imaging. 123Te is used for the production of radioactive 123I (with a half-life of 13.2 h) via the 123Te (p, n) 123I reaction, which is used in thyroid imaging and for in vivo medical studies using single-photon emission computed tomography (SPECT). 124Te is used for the production of both 123I and the PET isotope 124I via the 124Te (p, 2n) 123I and 124Te (p, n) 124I reactions, respectively,,,. The half-life of 124I is 100 h.
