2.   The conventional treatment for cancer is to bombard the tumour with gamma radiation.

3.   The conventional treatment for large tumours, deep within the body, is to bombard them with powerful doses of gamma radiation.

7.   But the critical mass later reassembled, starting another chain reaction and releasing more neutrons and gamma radiation.

8.   Exposure to gamma radiation can damage organs in the human body.

9.   Gamma-ray bursts have been known for three decades, but only in recent years have spacecraft sensitive to gamma radiation been studying them closely.
