A new contamination monitor with scintillation detection

Berthold Technologies designed for the measurement of radioactive contaminations on surfaces a new handheld contamination monitor. The instrument is based on innovative scintillation technology and has high sensitivity and uniform response over the entire detection area of 170 cm/sup 2/. This is achieved by utilizing a sophisticated reflector geometry. The monitor is capable of simultaneous and separate measurement of alpha-particles and of beta-gamma-radiation. The instrument was calibrated with more than 30 radionuclides which are commonly used in research or in nuclear medicine including also several short-lived nuclides like /sup 99m/Tc or /sup 18/F.
