Özet
The study was conducted in AL-Amal National Hospital for oncology in Iraq-Baghdad,
using I-131, the main objective of this study to make assess storage and delay system for
radioactive liquid waste in nuclear medicine, and the suitability of the system with the flow
volume of radioactive liquid wastes that discharge in Al-Amal National Hospital at the
present time and when the number of patients increases, data was collected using High
purity germanium reagent Radiation Detector. Nine sample of I-131 waste was collected to
calculate the Remaining activity before storage and before disposal, the results was in
range of 24498 Bq/L to 5.7 Bq/L in years from 2016 to 2022 in Average two reading in
each year. The discharge of the radioactive waste to the environment was done after 4
months which mean in 10 half-life of radioactive materials. This research prove that the
liquid radioactive waste can be discharged to the sewage system according to the
concentration limits of 100000 Bq/L that set by IAEA Agency. And it could permit to
increasing the number of patient with using the same system which held in AL-AMAL
hospital. Short-lived radionuclides such as 131-I with a half-life of about 8.04 days can be
drained into the sewage system at this discharge limit.
