Materials Required in Structures for Protection Against Nuclear Radiation

Abstract

To build a concrete nuclear shielding structure for an environment having 300-600 rads/sec of nuclear radiation intensity and reduce the radiation intensity to permissible limits, i.e. To 150 rads/sec at which there is not much of danger for the dwellings of any area and the environment is feasible. We are a nuclear state and our enemy has the same capability, so for second strike capability we must be able to protect our troops against the harmful effects of nuclear radiations so that they may reply the enemy with the same power. For that purpose our objective was to build our structure within the range between 1.7 to 4.7 km from the epicenter where a blast of 20 KT has occurred emitting radiations up to 3 MeV and blast waves applying 5 psi of pressure on structure that cause complete to moderate destruction of building in that region. So we designed a structure in that range for which we thought to design a concrete mix that will block the radiation bringing that to permissible range that is 150 rad/ sec and also absorb the shock waves by showing deflection in allowable region and strength similar to what is shown by our samples.
