Specifications include, but are not limited to: 24.2. The Ludlum Model 26-3 incorporates electronics and a time-tested GM detector in an ergonomically designed, ruggedly constructed, and water-resistant housing. The integrated instrument is cable-less thereby simplifying the process of frisking people and objects. The optimized configuration includes a standard 15.51 cm2 GM pancake, loud audible “click” output, and large auto-ranging LCD display with automatic LCD backlighting. Model 26-3 has the addition of a Units button that can display measurements in terms of mR/hr, µSv/h, dpm, or Bq. These features are combined in one convenient package making it easier than ever to detect alpha/beta contamination and measure gamma fields on personnel and objects. 24.3. Operation of the Model 26-3 is kept simple through the use of just three buttons that are strategically placed for one-handed operation. Three modes of operation RATE, MAX, and COUNT are available. The RATE mode will display current radiation levels in terms of rate. MAX mode captures the highest rate detected so it is possible to determine a peak rate during frisking operations when the display is not visible. COUNT mode allows the operator to perform a survey for a predetermined time. The user-selected units can display results in a measurement of scaler counts, activity (disintegrations), time-averaged rates, or even accumulated dose. An optional Ambient Dose Filter to correct the energy response is available (part number 2002-1050).; 9 EA Ludlum Model 26-3 Radiation Frisker
