Aims and objectives
Radiological imaging is an essential element of modern medicine,
which is used in diagnosis and treatment.
According to United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 20081 report radiation doses from medical exposures accounts for 98% of the contribution from all artificial sources and is now the second largest contributor to the population radiation dose worldwide.
the advancement of X-ray technology and its expansion in developing countries is causing extremely rapid growth in the annual number of procedures performed.
this resulted in...
Methods and materials
Radiation protection survey and quality assurance of X-ray installations
The radiation exposure levels during the operation of the radiological equipment were measured for the radiological installation and quality control and quality assurance protocols prescribed by Atomic Energy Regulatory Board for x-ray equipment was carried out by using PTW NOMAX multimeter to ensure the stability,
filtration and output consistency.
The machine setup,
procedure,
and exposure protocols were optimized to be within tolerance limits as per AERB guidelines and a specialized radiation awareness programme was conducted for...

Conclusion
The conventional chest examination was chosen for the study even though it is a relatively low dose examination but it is the most frequent pediatric radiography examination in all countries and,
due to very high frequency,
might produce a significant contribution to the collective effective dose.
The observed mean entrance surface dose (ESD) for chest radiography are higher than the National Radiological Protection Board (NRPB) DRL dose guidelines being the mean dose value instead of 75th percentile value as suggest for diagnostic reference level calculation...
