RAM Ion

RAM Ion

Excerpt - The RAM-Ion is a portable gamma meter designed for measuring wide range gamma radiation fields. Measurements are received by two internal energy compensated GM tubes and external probes: For beta gamma contamination (RG-10, RG-12), for high gamma fields (RG-40), and for Alpha contamination (PA-100M). The RAM R-200 can be used with a four-segment sturdy telescopic rod for the external gamma probe. The RAM R-200 meter and its external detectors include embedded microprocessors, data memory, and data communication. An audible indication is activated either by frequency fluctuations in accordance with the field strength or chirp for each measured pulse. The RAM R-200’s auto-ranging meter utilizes a combination display consisting of a smoothed digital readout for minimum fluctuations, and a two-decade analog bar graph for fast response.

RAP Probes

RAP Probes

Excerpt - The CsI (Tl) crystal used in Radiation Alert® Probes has a higher atomic number, is more rugged, and less hygroscopic than a typical Nal detector. The improved gamma ray absorption allows a thinner crystal to be used, effectively reducing the background count rate.

  • Thin-crystal (1 mm) optimizes sensitivity to low energy gamma radiation while minimizing sensitivity to higher energies.  An excellent detector for Iodine-125 and suitable for thyroid uptake measurements.
  • A 0.25-inch crystal optimizes this for the detection of special nuclear material (SNM) such as U-235, or related isotopes  such as Am-241, much like a mini-FIDLER.
  • Superior to a 1 x 1-inch NaI detector, this is a great choice for an all-around gamma and x-ray detector. Optimal energy  range of about 20 keV to 2 MeV. Highest efficiency for a broad spectrum of gamma-emitting isotopes.
