The type R rod is used for calibrating well type NaI(Tl) detectors. It is constructed of high strength plastic and is offered in three sizes: 5” high x 0.625” diameter (127 mm x 15.9 mm), 5” high x 0.5” diameter (127 mm x 12.7 mm) and 2.95” x 0.5” diameter (74.9 mm x 12.7 mm). The active diameter of the rod standard is 0.187” (4.75 mm).
