Wiens has a Ph D in Physics, with a minor in Geology.
His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells (1).
Understand how decay and half life work to enable radiometric dating.
When the damaged cells die, they are broken down and eliminated by the body’s natural processes.
No, radiation therapy can also damage normal cells, leading to side effects.
In most cases, the information is used by physicians to make a quick diagnosis of the patient's illness.
