DETECTING RADIATION
Geiger Mueller tubes are simple devices that detect and measure radioactivity. The original design by H. Geiger and E.W. Mueller in 1928 hasn't change very much. The basic sensor functioning remain the same. A cut away drawing of a typical Geiger Mueller (GM) tube is shown in Figure 2. The wall of the GM tube is a thin metal (cathode)cylinder
RADIATION SAFETY: LEAD SHIELDING GUIDE Radiation Safety: Lead Shielding Guide. Purchase Lead Sheet (s) for Gamma Shielding: Shielding reduces the intensity of radiation depending on the thickness. This is an exponential relationship with gradually diminishing effect as equal slices of shielding material are added. A quantity known as the halving-thicknesses is used tocalculate this.

Ion Generator Kit (Kit; Requires Assembly) 12VDC 500 mA - RADIATION MEASUREMENT The maximum dead time for our GM tube is 90 microseconds (or .00009 seconds). There is a mathematical formula for adjusting a Geiger counter read out to compensate for the GM tube's dead time. However the adjust is so small that for practical applications it can be ignored. High-end nuclear work will take a tube's dead time intoconsideration.
GEIGER COUNTER CALIBRATION SERVICE In House Calibration is $45.00. In House Calibration. Geiger Counter must be returned along with its original wand (if applicable). This Charge does not include any repairs to the Geiger Counter, if repairs are needed that would be a separate charge that would be determined at THERMOELECTRIC POWER GENERATOR In 1821 Thomas Johann Seebeck discovered the thermoelectric effect, which is the generation of electric current from heat. He discovered when a junction of two dissimilar metals are heated through a temperature gradient, the junction produces a small but measurableelectric current.
