The Radiation Alert® Frisker CAUTION: The mica surface of the Geiger tube is fragile and should be handled with care. Be careful not to let anything penetrate the screen. The Radiation Alert® Frisker uses a 2-inch, thin window Geiger tube, commonly called a “pancake tube.” The screen on the back of the Radiation Alert®... -
Page 5: Chapter 2: General Operation
Chapter 2: General Operation Starting the Radiation Alert® Frisker Before starting the Radiation Alert® Frisker, install 2 standard AA alkaline batteries in the battery compartment located in the lower rear of the handle (Figure 1(1)). To start the Radiation Alert® Frisker, set the power switch to On (I) or Audio (A). The Radiation Alert® Frisker will then beep and begins a 6-second system check. -
Page 6: Triggering The Alarm
Setting the Alarm Level To set the alarm level on the Radiation Alert® Frisker, hold down the backlight button for 3 seconds to enter into the alarm set screen. The units of measure for the alarm will be displayed as the same unit of measure you have chosen for the operation of the unit. -
Page 7: Chapter 4: Using The Radiation Alert® Frisker
Chapter 4: Using the Radiation Alert® Frisker Checking for Surface Contamination To check a surface, hold the detector window close to the surface (1 cm - 1 in), and read the count rate. Be careful not to touch the Frisker to any potentially contaminated surfaces to prevent contaminating the unit. Move the Frisker over the surface in a grid formation at a speed of about 1 inch every 1-2 seconds. -
Page 8: Chapter 5: Maintenance
Chapter 5: Maintenance The Radiation Alert® Frisker requires regular calibration and careful handling to assure good measurements. Use the following guidelines to maintain the instrument properly. Calibration We recommend that the Radiation Alert® Frisker be calibrated annually, or as often as your regulations require. The best way to calibrate is using a calibrated source at a calibration lab. -

Chapter 6: Troubleshooting The Radiation Alert® Frisker is a highly reliable instrument. If it does not seem to be working properly, look through the following chart to see if you can identify the problem. Problem Possible Cause Action Display works, but no counts defective Geiger tube Look through the window to check the are registered... -
Page 10: Chapter 7: Taking Basic Measurements
Chapter 7: Taking Measurements The Radiation Alert® Frisker will not detect neutron, microwave, RF (radio frequency), laser, infrared, or ultraviolet radiation. All of our instruments are most accurate for Cesium-137 and isotopes of similar energies. Some isotopes detected relatively well by most Geiger counters are Cobalt-60, Technicium-99M, Phosphorous-32, Strontium-90, and many forms of Radium, Plutonium, Uranium, and Thorium. -
Page 11: How To Determine Alpha, Beta, Or Gamma Source
Geiger counters can detect the four main types of ionizing radiation: alpha, beta, gamma, and x-rays. Some detect only gamma and x-rays. Our instruments are calibrated to Cesium 137, but also serve as excellent indicators for many other sources of ionizing radiation. Gamma and x-rays are measured in milliroentgens per hour (mR/hr), microsieverts (µSv/hr), or millisieverts (mSv/hr). -
Page 12: Chapter 8: Unit Conversions
Chapter 8: Unit Conversions Radiation Measurement Units Several different units are used to measure radiation, exposure and dosage. Roentgen is the amount of X-radiation or gamma radiation that produces one electrostatic unit of charge in one cc of dry air at 0° C and 760 mm of mercury atmospheric pressure. One thousand milliroentgen (1,000 mR)= 1R. -
Page 13: Chapter 9: Glossary Of Terms
Chapter 9: Glossary of Common Terms Background Radiation Naturally occurring radiation is always present. It includes high energy gamma rays and particles from the sun and outer space and alpha, beta, and gamma radiation emitted from elements in the earth. CPM (counts per minute) The unit of measurement usually used to measure alpha and beta radiation. -
