摘要:
An epoxy resin composition which is cured transparent product having high neutron shielding capability, comprised by an epoxy resin without any not transparent inorganic substances and a hardener and characterized by said composition's viscosity at ambient temperatures is below 7000 mPa·s and said composition is curable at said temperatures.
摘要:
A radiation shielding material for intercepting not only .gamma. rays and x rays but also neutrons, comprising sulfur, iron oxide powder, lead oxide powder, gadolinium oxide powder and hydrogen-occluding alloy powder; and a process for preparing the radiation shielding material.
摘要:
A radiation shielding material prepared by thermally melting a mixture of sulphur and iron oxide powder to react the mixture thoroughly so as to obtain a melt, adding lead oxide granules to the thus obtained melt to mix them together thereby dispersing the former in the latter and then forming the whole mass into a predetermined shape.
