What is the maximum operating temperature (degrees C) for the palmRAD meters?
Do your instruments measure x-rays? Our Geiger counters detect x-rays, but may not be accurate in measuring the dose rate. This is because an x-ray is usually a short concentrated burst of radiation. A Geiger counter measures by detecting individual ionizing events in its Geiger tube. The events during the X-ray usually occur so fast that the instrument cannot detect all of them, giving a reading that does not reflect the full amount of radiation. For a true dose rate, an ionization chamber would be required. Medical and dental x-ray machines sometimes have “scatter,” or leakage in directions other than the target. Inadequate shielding can cause this scatter to reach personnel, resulting in unnecessary exposure. To screen for scatter, you can place PalmRAD 907 or Geiger in a location you want to test while the x-ray machine is activated. If there is scatter, if the instrument is in Audio mode, you will hear a rapid burst of chirps, or clicking, and it will produce a higher-than-normal
