Kegunaan isotop germanium
- 72Ge and 74Ge are used to produce the radioactive isotopes 72As and 74As, with half-lives of 26 h and 17.8 days, respectively. The arsenic nuclei can attach to tumors and the decay of these isotopes is used to image the location of cancerous tumors in vivovia the 72Ge (n, p) 72As reaction and the 74Ge (n, p) 74As reaction. 70Ge, 72Ge, and 74Ge have all been used to produce the medical radioisotope 73Se via the 70Ge (4He, n) 73Se reaction, via the 72Ge (4He, 3n) 73Se reaction and via the reaction 74Ge (4He, 5n) 73Se, respectively.
