Results obtained for both absorption and scattering show that Marbolite is a considerably better shielding material than natural white marble. As compared to lead, Marbolite is about one third as effective in absorption but has the advantage of producing less scattering. Calculations based on the cost of these materials show that for the same percentage absorption, Marbolite is about eight times cheaper than lead and about four times cheaper than that of natural white marble. The ease of handling and fabrication in any desired shape (especially to make interlocking bricks) coupled with its low cost makes Marbolite, au excellent material for temporary shielding in laboratories, where shielding arrangements are changed frequently to suit the experiments in hand. Due to its acid and alkali resistant properties, and the fact that it can be easily decontaminated due to its polished surface, Marbolite appears especially suitable for radiochemical or other similar laboratories where chemical reactions with radioactive isotopes are performed.
