Abstract:
Nowadays it is noticed that increasing attention has been paid to radiation
protection. There were many studies on evaluating radiation protection in
Sudanese hospital and there was protection defect in most of them.
This thesis is concerned with evaluate the radiation protection status in
Omdurman health centers and was conducted in Aldaw-Hajoj Abo-Sed Wad-
Nobawi and Alrakha centers.
The study has been carried out during the period from February 2009 up to
October 2009. The data was collected by the way of measuring patient dose
using TLD. Radiation exposure surveys was carried out using survey meter
and quality control test using its tools .Finally collect other data using
questionnaires.
The patient dose was measured to 108 patients in four centers in Omdurman
city. The patient data, dose and questionnaires were statistically analyzed
and were computed and graphically represented.
The mean ESD in this study found to be 0.29 mSv was the mean kVwas59.9
the mean mAs was 9.6 the mean age was 42.6 years the mean BMI was
27.1.
For chest exam the mean ESD was 0.25mSv and for upper limbs 0.3mSv
while in lower limbs exams was 0.4 mSv.
The results of this study intended to evaluate the current status of radiation
protection in different centers in Omdurman. The lowest radiation dose was
on Abo-Sed (mean 0.22 mSv) and the highest dose was on Aldaw-
Hajoj(mean 0.33).In Wad-Nobawi(0.26) Alrakha (0.30).

There was multiple cases dose on the four centers was higher than the DRL
according to NRPB on Abo-Sed (10%) Aldaw-Hajoj (55%).In Wad-
Nobawi(45%) Alrakha (55%).
The protection status associated with co-patient was good in three centers
and high on Aldaw-Hajoj center (reception dose 100μSv). The dose for
technologist was acceptable in two centers as recommended by (ICRP) and
high in one center (Alrakha 21.12mSv per year).
The knowledge of medical doctors in the field of radiation protection
concepts was very shallow. Therefore, unnecessary exposure and
optimization and justification principles are hard to be applied
