10–20, 1990 – a radiological accident that occurred at the Clinic of Zaragoza, in Spain. In the accident, at least 27 patients were injured, and 11 of them died, according to IAEA. All of the injured were cancer patients receiving radiotherapy. October 26, 1991 – Nesvizh, Belarus – An operator at an atomic sterilization facility bypassed the safety systems to clear a jammed conveyor. Upon entering the irradiation chamber he was exposed to an estimated whole body dose of 11 Gy, with some portions of the body receiving upwards of 20 Gy. Despite prompt intensive medical care, he died 113 days after the accident. June, 1992 - A Ph.D. student at the Institute for Animal Health in the UK, now the Pirbright Institute, received an approximately 2.5 Gy dose from 32P labelled organo-phosphate as part of an experiment to label virus infected cells. The company shipping the material had supplied over 1000 times the amount and the receiving site did not have adequate monitoring facilities for source material. November 16, 1992 – Indiana Regional Cancer Center – After treating a patient with HDR brachytherapy, personnel ignored alarms indicating high radiation levels and an available radiation survey meter was not used to confirm or rule out the area alarm's signal. A radioactive pellet of 192Ir had broken off inside the patient during treatment. The patient was transported back to a nursing home where the catheter containing the radioactive pellet fell out four days later. The patient received a thousand times the intended dose and died several days later. November 19, 1992 – A 60Co source (which was used for an agricultural project) was taken home by a worker from a well within a construction site which used to be part of an environmental monitoring station in Xinzhou, Shanxi (China). This resulted in three deaths and affected 100+ people. A woman was exposed to radiation while nursing her sick husband. Her dose was estimated to be 2.3 Gy by means of a blood test 41 days after the accident, 16 years after the accident the woman has been subject to premature aging which may be a result of her radiation exposure. Her then unborn child (induced at 37 weeks, birth weight 2 kilograms) got a dose of almost 2 Gy in utero, and at the age of 16 the child had an IQ of 46. August 31, 1994 – Commerce Township, Michigan
