Johnson, A N; Prisco, A J

A method is described for continuously sorting radioactive material from nonradioactive material comprising the steps of providing material containing radioactive and nonradioactive material, placing the material in a first detection station, providing means at the first detection station for detection radiation above a first predetermined level emanating from the radioactive material and removing material which is detected as being radioactive at the first detection station, conveying the remainder of the material to a second detection station, providing means at the second detection station for detecting radiation above a second predetermined level emanating from the remainder of the material, removing material which is detected as being radioactive at the second detection station, placing the remainder of the material in a container, delivering the remaining material to a third radiation detection station, providing means at the third detection station for detecting radiation which is at a predetermined level, and storing the container if radiation is not detected at the third detector station.
