Product Description
The Radiation Alert Inspector is a hand-held, microprocessor-based radiation detector that detects potentially harmful ionizing alpha and beta particles, and gamma and x-ray radiation, has a four-digit, LCD digital display of millirem (mR) per hour, and function indicators. This radiation detector can detect low levels of the four main types of ionizing alpha and beta particles, and gamma rays and x-rays over automatic operational ranges. It is optimized to detect small changes (low levels) in radiation levels and to have high sensitivity to many common radionuclides.
The Inspector counts ionizing radiation changes, and the unit of measurement is selected and displayed using the mode switch. The display shows various indicators, based on the mode setting, the function performed, and remaining battery power. These include low battery, alert, timer, total mode (to see the number of times a reading should be multiplied by to obtain the correct radiation count), calibration mode, utility menu (timer, calibration, alarm set mode), and units of measurement. It has automatic operational ranges for a variety of radiation detection. A red, flashing counter and a beep noise indicate each ionizing radiation change event. The display updates every three seconds. At low background levels, which are typical in a geographic area, the update is the moving average for the most recent 30-second time period. The time period for the moving average decreases, as radiation levels increase. The radiation detector has a 2”, halogen-quenched, uncompensated Geiger Mueller (GM) tube with a thin, mica end window for sensing ionizing radiation. A radiation symbol on the front label marks the center of the detector. It is used for surveying naturally occurring radioactive material (NORM) contamination, gross wipe counting, contamination inspection of packages, equipment, and people, regulatory inspections, and for low energy radionuclide detection. This detector has a utility menu on the back of the unit. The menu has a three-second response, and switches the detector from mR/hr and counts per minute (CPM) to μSv/hr and counts per second (CPS). It also can reset the calibration factor to 100, adjust calibration, and reset all settings to the default factory setting. The radiation detector has an audio indicator with an internally mounted beeper that can be turned off for silent operation. The Inspector has a one-year, limited warranty for materials and craftsmanship, and a 90-day warranty on the GM tube.

4.0 out of 5 stars Very nice detector March 24, 2012
By Joe in Memphis
I have the Inspector EXP+, it is the same exact detector, but with an external probe on a 40" cable. They both use the LND-7317 "pancake" Geiger Muller tube, and are VERY sensitive, especially to Alpha. The LND-7317 GM tube is much more sensitive than the smaller LND-712 GM tubes that a lot of the other Geiger counters of this size are using. Let me put "much more sensitive" into perspective. I also have a VERY NICE Mazur PRM-8000 that uses the LND-712 GM tube. I just did an hour long count with both detectors sitting on my window sill of background radiation, the LND-712 based detector registered 1,020 Counts or 17 CPM. The LND-7317 based detector (the Inspector EXP+) registered 2,243 counts, or 37.38 CPM. I also tested a Uranium Glass bowl with both of them, the LND-712 based detector registered 430 counts over 10 minutes for 43 CPM, the LND-7317 based detector (the Inspector EXP+) registered 10,960 Counts, for 1,096 CPM. I would say that is "much more sensitive". The Inspector+ will detect and count Alpha, Beta, Gamma, and X-Ray. It is a no frills (as far as the programming goes) solidly built detector that you can turn on, wait 30 seconds until it beeps (to achieve statistical accuracy), and you are ready to measure in CPM, CPS, mR/h, uSv/h. It IS that simple. It has an internal counter that can be set from 1 minute to 24 hours to take long surveys, and an alert that can be set in either CPM or mR/h. The alert range is 0~ 160,000 CPM or 0~50 mR/h. The display is not lighted. It comes with a "Certificate Of Conformance" that warrants the factory calibration for 12 months, and a case. The instruction manual is on a smaller than normal sized CD ROM. It is a very well laid out manual. I highly recommend either the Inspector+, or the Inspector EXP+. If you are looking for an LND-712 based detector the Mazur PRM-8000 is probably the best you will find. As a side note, if you are interested in the study of radiation or the proper use of Geiger Counters, check out antiprotons youtube page, there is a LOT of good information in his videos.
