Nucl. Med. Technol.1978 Jun 01; 6 AB - A design for a high density, moderate strength concrete as an alternative to lead, for shielding radiations below 1 MeV is presented. When space is not of primary concern, high density concrete may prove an economical method of shielding the radioactive wastes discarded from the average nuclear medicine department. The concrete described is limited to small projects only because of its low structural strength. High strength concrete of a more complex formula, which has long been a favored material in high radiation shielding, is available but at additional costs. Using this information, the consultant in nuclear medicine may enhance the efficient traffic of radioactive wastes through preplanned waste areas constructed with high density concrete.
