DOSE CA L IBRAT ION LINEATOR Simulates eight different source strengths — using only one source MOLY ASSAY SHIELD M oly Assay Shields are a convenient method to verify a unit dose. Whether working with syringes or vials, either unit will fit into the well chamber of any Atomlab Dose Calibrator. The leaded shields are cradled by a metal holder for easy handling to ensure proper placement inside the chamber. Model 086-435 shown SPECIFICATIONS: • Simplifies compliance with NRC and state requirements • Checks linearity without sample decay or fractioning • Covers diagnostic or therapeutic quantities in a single pass 086-435 Moly Assay Shield, Syringe Dimensions: 9.125" h x 2.125" dia (23.2 x 5.4 cm) Lead Shielding: .3" thick (7.6 mm) 086-423 Moly Assay Shield, Vial Dimensions: 3.5" h x 2" dia (8.9 x 5.1 cm) Lead Shielding: .3" thick (7.6 mm) 086-435 086-423 T he Lineator is a simple device to accurately and reliably verify the linearity of your dose calibrator. Test results are available in minutes, without waiting days for decay, making it feasible to perform a linearity test more often. Early identification can prevent problems before they occur. The Lineator is a set of five tubes. Four tubes are used to perform the test and an interchangeable tube is used depending on the dynamic range needed to cover. To perform a linearity test, insert a source of Tc-99m of the maximum activity to be measured into the central tube, then place the tube into the chamber of your dose calibrator and count. The remaining lead-lined tubes are placed, one at a time, concentrically over the central tube and counted individually or in combination. The readings are then normalized with predetermined factors, and the degree of linearity can be seen virtually at a glance. Using only one source, the Lineator can simulate up to eight different source strengths. Each outer tube absorbs a portion of the source radiation and reduces the effective source activity seen by the dose calibrator.
