Reta-gamma sensitive micro counter tubes of the Maze type were developed for radioisotope tracer work. The tubes can be sterilized and used in humans for medical diagnosis by radioisotope uptake and for biological research. Flexible lead wires are hermetlcally sealed to the metal-encased glass tubes. Volumes range from 2 mm/sup 3/ to 850 mm/sup 3/, and wall thicknesses range from 0.4 Mev to 0.2 Mev. Thinner windows have been made in some types. Life is >10/sup 7/ counts, with heliuni filling. Practical beta dotection sensitivity ls 0.001 to 0.01 mu at 1.0 cm distance in air. Similar tubes l.0 mm o.d., 6 mm to 30 min long have been made for inter- changeable use in needle-type probes Techniques of construction and typical beta response characteristics to Sr-Y/ sup 90/, Co/sup 60/, Y/sup 90/, and Ra g rays are given. 3 figures.
