LabLogic Systems is offering a free source calibration certificate worth £49 to purchasers of its radiation contamination monitors until the end of April 2006
The Geiger Muller-based Rad Monitor GM1 is a general-purpose monitor for 14C, 32P, 33P and 35S.
Its GM tube detector has a 28.5mm (1.125 inches) total effective area and a window thickness of 1.5-2.0mg/cm2, with a unique thin screen that protects the end window and an 86% open area.
Model GM2 has the same specification but with a larger end window (45mm/1.75 inches) that makes it ideal for detecting soft beta emitters such as 14C and 35S on hands, clothing, and benchtops.
The variant version GM2-P, designed for monitoring surfaces, has a pancake probe, a rubberized grip handle and a large diameter GM tube mounted at a slight angle.
Completing the range is the sodium iodide crystal-based Rad Monitor SD10, which has a high sensitivity scintillation probe that gives superior performance compared with GM instruments for detecting 125I and 32P.
