Radiation Detection Instruments
Contact: Mark Linsley, mel18@psu.edu814-865-6391
Radiation detection instrumentation is essential for ensuring worker safety and preventing the spread of radioactive contamination. Portable survey instrumentation is required of all users of dispersible radioactive material and some sealed source and x-ray users. Survey instruments are divided into two groups: count rate survey instruments for contamination monitoring, and dose rate instruments for measuring the intensity of the radiation field. Each of these will have a variety of options to choose from ranging from analog or digital, scale readout, cable connectors, and type of detector.
Users of higher energy beta emitters such as C-14, P-32, P-33, and S-35, must use a count rate survey meter equipped with a Geiger-Mueller (GM) probe. These probes are can be either an End-Window or Pancake style. The Pancake GM probe has the greater detection efficiency than the End Window probe.
Users working with low energy x-rays and gamma emitters, such as I-125, must use a count rate survey meter equipped with a special probe, such as a sodium iodide crystal, designed for detecting these types of radiation.
Listed below are manufactures and distributors of radiation detection instrumentation and supplies. This list does not include all possible suppliers and is only intended to provide information on a selection of instruments from the major suppliers that are adequate for laboratory use.
We STRONGLY encourage you to contact Environmental Health and Safety before purchasing any instrument to ensure you have selected the proper configuration suitable for your needs.
