Radioactive iridium wires implanted into a man's neck to treat a lymphatic cancer. Radioactive implants are used to deliver a controlled dose of radiation to a localised tumour. Other types include radium needles (used to treat cancers of the larynx) and pellets of caesium-137 (contained in an applicator for insertion into the vagina or uterus to treat cancers of cervix, uterus or vagina). Radioactivity from such implants travels distances varying from a millimetre to up to 2 centimetres. Needle and wire implants are left in place for typical durations ranging from 24 hours to 1 week.
