Radioactive Liquid Waste Treatment

Radioactive liquid wastes usually contain high, medium, or low amounts of radioactivity. The means of treating high-volume-low-activity waste is very different from the means of treating small-volume-high-activity waste. Medium-level waste is treated to convert it into high- and low-activity waste. Low-activity wastes are treated to remove radioactivity, then discharged to the environment in amounts well below permissible limits. This is the dilute and disperse philosophy. High-activity wastes, because of their hazard, must be concentrated, contained, and re moved from man's environment. Definitions of waste categories (ASI 1967; IAEA 1970a) are given in Table 8.7.1.
