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.

Dosimeters

Sentry

Sentry

Excerpt - The Radiation Alert Sentry Personal Alarming Dosimeter and Rate Meter is designed to ensure the personal safety of personnel that work in occupations with potential x-ray or gamma exposure. The pocket sized unit has built in memory for recording data points for the purpose of tracking exposure. The Sentry Software option enables you to generate incident reconstruction for analysis. The software also enables you to easily set the vibrating and audio alert to your desired levels for dose and dose rate. Use the audio switch to choose between an audible click with every count taken, or a discreet silent mode that can be augmented with the use of headphones.

GammaPAL

GammaPAL

Excerpt - The Gamma PAL is a complete portable measuring system for analyzing radiation contamination in food, such as milk, meat, fish, grain, fruit, and vegetables, as well as soil, water, air and other materials. It allows users to directly and easily perform quick, reliable measurements in Bq/l or Bq/kg and identify the isotopes present in potentially contaminated material using one of three pre-calibrated geometries.
