7 Page 7 of 7 Dial Settings and Source Containers (Glass Vial, Glass Syringe, etc. The Atomlab Dial (DV settings enable the software to convert ion chamber current into a displayed activity value for the isotope corresponding to the DV selected. The displayed activity value is directly proportional to the DV. The isotope s source container is either a vial or syringe; the composition of the vial or syringe MAY influence the accuracy of the activity measurement. The DV supplied in the Atomlab User Guide (Instruction Manual, or pre-programmed into the front panel isotope keys, are calibrated for use with the source material in an un-shielded plastic syringe (nominal 1mm wall, while hanging in the supplied source dipper syringe support. For isotopes contained in sealed long lived QA sources (Cs-137, etc., the DV supplied are calibrated for use with type Vial E epoxy sources or equivalent. Accurate measurement of unsealed sources in any other configuration must be with a new Container Dial CDV, determined by the USER with the following procedure. During following steps, set DV to the Atomlab published value. Container with no source material 1 Assay a quantity of isotope source material in a plastic syringe, nominal wall thickness of 1mm, record as (Plastic Syringe Activity1. Transfer part or all of the source material from the plastic syringe into the empty Container. 3 Assay the Container with the isotope source material, record as (Container Activity. 4 Assay the partial or empty plastic syringe for residual activity, record as (Plastic Syringe Activity. 5 Calculate the Container Dial for use with isotope assayed in that type of container, CDV = DV * (PSA1 - PSA / (Container Activity where PSA = Plastic Syringe Activity Container with source material 1 Assay Container with the isotope source material, record as (Container Activity1. Transfer part or all of the source material from the Container into a plastic syringe, nominal wall thickness of 1mm. 3 Assay the plastic syringe with the isotope source material, record as (Plastic Syringe Activity. 4 Assay the partial or empty Container for residual activity, record as (Container Activity. 5 Calculate the Container Dial for use with isotope assayed, CDV = DV * PSA / (CA1-CA where PSA = Plastic Syringe Activity and CA = Container Activity. Typically, for glass wall source Containers, CDV will be higher than DV when the isotope has a significant portion of low energy photons in its emission spectrum.. included implies low energy photon from electron interaction in saline 5.
