“…Analysis of the 131 I activity levels in the wastewater samples collected from a university hospital's nuclear medicine facility in Brazil was conducted. The findings of the gamma spectrometry measurements and analyses conducted on the collected sewage samples revealed that the estimated values (EV) for activity concentrations obtained for 131 I in July were significantly lower than those obtained in July (8.78×10 3 Bq/m 3 ), September 2016 (9.80×10 3 Bq/m 3 ), and February 2017 (1.14×10 4 Bq/m 3 ) were all below the exemption level (EL = 1.90×10 4 Bq/m 3 ) [17].…”

The research was conducted at one of Iraq's nuclear medical facilities in Baghdad, which uses radioactive iodine (I-131) to treat thyroid patients, the major purpose of this research was to meet the national legal limit for the release of radioactive liquid waste into the environment, a high purity germanium reagent radiation detector was used to evaluate nine iodine I-131 samples. From 2021 and 2023, the concentration of waste prior to storage and disposal was between 24498 Bq/L and 5.7 Bq/L. Short-lived radionuclides, such as I-131 with an 8.04-day halflife, may be released into the sewage system in line with Iraq's Nationally Approved Limits and Austria's International Atomic Energy Agency (IAEA). Moreover, it is stored for 10 times the half-life, or four months, until the choice to release it into the environment is made.
