Homework Answers
Several species of the same chemical element with different
masses whose nuclei are unstable and release excess energy by
spontaneously emittion of radiation.
can be traced with a Geiger counter.
some useful for medication purpose are:-
1)cobalt-60 is extensively employed as a radiation source to arrest
the development of Cancer.
2)carbon-14, used in a breath test to detect the ulcer-causing bacteria Heliobacter pylori.
3)Iodine-131 has proved effective in treating hyperthyroidism.
