毒性Radon is derived from the radioactive decay of radium. It is highly toxic and emits ionizing radiation. Lead shielding must be used in handling and storage. Radon has appeared naturally in the basements of homes, causing some concern for the residents. The primary uses are as a cancer treatment, a tracer in leak detection, in radiography, and in chemical research.
