The College of Education for Pure Sciences at the University of Basra discussed a master's thesis on environmental radiological rationing for schools and hospitals in Al-Diwaniyah Governorate using the thermoluminescence technique.
The message presented by the researcher (Assaad Sayah Hassan) included
The aim of this study is to determine the rate of gamma ray doses resulting from the natural background radiation of schools, hospitals and health centers in Al-Diwaniyah Governorate using the thermoluminescence technique. There are many sources of error in the thermoluminescence measurement system, and vigorous efforts are being made to reduce the effects of inaccuracy for the purpose of controlling these systems, so they have been studied. Measurement of radiation doses. The loss rate of thermoluminescence quantifiers at different storage temperatures after irradiation was calculated. After verifying the validity of these systems for radioactive environmental monitoring programmes.
Seventy-eight different sites were selected in terms of size and location, including 49 different schools and 29 government hospitals and health centers. The measurements were used to measure the gamma rays emitted by the natural background radiation. It was found that the average gamma ray dose for schools ranges between 8.06-4.55 µ rad/h at a rate of 6.38 µ rad/h.
The results also showed that the average gamma ray dose for hospitals ranged between 7.95-4.48 at a rate of 6.01 µ rad/h and for health centers ranged between 7.44-5.38 µ rad/h at a rate of .6.10 µ rad/h
The study concluded
The environmental radiation rationing of schools, hospitals and health centers in Al-Diwaniyah Governorate was studied using the thermoluminescence technique. We found that the average gamma ray dose in schools was 6.38µrad/h, and this dose is considered normal and within the permissible level and is considered not radioactively polluted. We also found that the average gamma ray dose in Hospitals and health centers by 6.01 µrad/h. This dose is considered normal and within the permissible level, and it is considered not radioactive.
