title="Radioactive discharge from patients with thyroid cancer under 131I treatment and its safe disposal to the public sewer system",
abstract=" Introduction:  The treatment of thyroid cancer using unsealed sources of radioactive materials is usually associated with a large amount of  131 I. The major problem for hospital treatment of these patients is the disposal of waste which requires special protection.   Materials and methods:  152 patients with thyroid cancer admitted to the nuclear medicine department of Said Al-Shohada Hospital for  131 I treatment were studied. Exposure from patients was measured using a Victorian 190F survey dosimeter.  131 I excreted from these patients during isolation was calculated.   Results:  More than 70% of administered  131 I was excreted after 24 hours, 90% after 48 hours and 96% after 72 hours of the isolation. The mean biological half-life of  131 I in patients with thyroid cancer was found to be 13.9\±1.9 hours. There was no significant difference between the mean effective half-life in patients treated for the first time and the second time at 95% significant level.  Conclusions: The results of this study showed that the difference in the discharge rate of  131 I from patients with thyroid cancer receiving first and second treatment was not significant. The mean discharge rate after the first 24 hours was more than 70%, and it was more than 96% after the third 24 hours of drug administration. The results can be used to design a safe collecting and discharge method of the waste.",
