The principal objective of radiation protec­tion is to ensure that the dose received by any individual does not exceed the applicable M.P.D. values.We will discuss in this paper the presents recommendations and technical information related to the design and installation of struc­tural shielding with taking into account the concept of Maximum Permissible Dose equi­valent (MPDl as expressed and given in the Medical Journal of the National University of Iran, Vol. 3. No. 1, January 1975. 
The numerical values of the MPD are such that the probability of adverse biological effects is extremely low in light of the present scien­tific knowledge of Radiation Biological Effects (R.B.E.) in safety use. It includes a discus­sion of the various factors to be considered in the selection of appropriate shielding mate­rials and in the calculation of barrier thick­ness. The paper is prepared after reviewing many literatures: i.e., all NBS, ICRP, ICRU, NCRP, published Journals and reports, all in­ternational recommendations in this subject for ihe use of radiologists, radiological physicists, health physicists, inspectors and regulatory personnel, architects, hospital administrators in the light of planning and designing new faci­lities, remodelling existing facilities, possible future needs for new equipments, higher radia­tion source of machine and even increasing work load.
