Wipe Test Fixture for ASM Survey Meters

Effectively detects removable radioactive contamination (wipe testing)
High 99mTc efficiency
Direct reading capability with
ASM-990 and 992 Advanced Survey Meters and isotopic calibrations
Removable wipe test sample holder positioned below shielded probe, minimizes background radiation and maximizes wipe test counting

The Wipe Test Fixture for the
ASM-990 Advanced Survey Meter uses a high efficiency NaI(Tl) scintillation probe in conjunction with a lead shielded sample holder. It employs a removable wipe test holder or tray positioned below the
shielded probe. Under these conditions, background radiation is minimized and wipe test counting is maximized.

When used with the ASM-990, or 992 advanced survey meters, the wipe test fixture is able to be calibrated to various other isotopes and thereby expand its role as a wipe test counter. In performing this role, the ASM-990 survey meter
consolidates the functions of three
products.

The Wipe Test Fixture is designed to precisely measure 99mTc within 30 seconds at efficiencies far surpass-ing those currently in use. It can count effectively in rate mode and display in any known unit, including “dpm 99mTc” or “μCi 99mTc”.
