Product Features

  • Radiation detector used when quick readings that call for heightened sensitivity are needed to survey levels of potentially harmful ionizing particles and rays in the environment, such as in first responder, personal safety, surface and food contamination detection, naturally occurring radioactive material contamination (such as granite), and in the scrap metal, and uranium mining industries
  • Device is not energy compensated, and allows for detection of ionizing radiation types such as alpha and beta particles, and gamma rays and x-rays
  • Large, 2-inch, halogen-quenched, pancake-shaped Geiger-Mueller (G-M) tube for heightened sensitivity to radiation detection
  • LCD lighting displays digital reading of current radiation level in milliroentgens (mR) per hour (mR/hr), or counts per minute (CPM); or when SI (metric) units are selected, in microSieverts (μSv) per hour (&mu:Sv/hr), or counts per second (CPS)
  • Provides total count for a timed period (from one minute to 24 hours) to determine average CPM over a period of time for higher accuracy and precision measurement

Product Description

The International Medcom Inspector Alert is a hand-held radiation detector that has energy compensation to detect potentially harmful ionizing alpha and beta particles, and gamma and x-ray radiation, and has a large Gieger-Mueller (G-M) tube, automatic compensation, an accumulated total timer function, and LCD digital display of milliroentgens (mR) per hour (mR/hr), counts per minute (CPM), microSieverts (μSv) per hour (μSv/hr), or counts per second (CPS). This radiation detector has the ability to detect 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 Alert radiation detector has a large halogen-quenched, G-M tube with a pancake-shaped mica end window for sensing ionizing radiation. It automatically compensates for G-M tube dead time, which is the brief period of G-M tube insensitivity after quenching, and is designed to not jam in high radiation fields. The radiation detector has an audible alert feature that signals when radiation reaches a user-defined level. It features a 4-digit LCD digital display with mode indicators that updates every three seconds, and can be muted. It displays current radiation level in mR/hr, or CPM; or when SI (metric) units are selected, in μSv/hr, or CPS. The detector counts ionizing radiation changes at 3-second intervals. 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 at normal levels. A moving average helps smooth out short-term data fluctuations. The time period for the moving average decreases, as radiation levels increase. Users can select a fast 3-second averaging period. A red, LED light flashes with each ionization event. The instrument has an accumulated total count and timer function that provides total event count for a timed period (from one minute to 24 hours) to determine average CPM for higher accuracy. The radiation detector has an audio indicator with an internally mounted beeper that can be muted. Total timer, audio on/off and units of measurement are selected and displayed using the front-panel mode indicators. The utility menu allows modification of the default settings for several operating parameters.

The Inspector Alert works in laboratory and field applications. It is used for surveying levels of potentially harmful ionizing particles and rays in the environment such as in first responder, personal safety, surface and food contamination detection, naturally occurring radioactive material contamination (such as granite), and in the scrap metal, and uranium mining industries. It comes in a protective hard carrying case. The Inspector Alert has Conformite Europeene (CE)-certification. The Inspector Alert cannot be returned.

Radiation detectors, sometimes called Geiger counters or G-M counters, can detect a broad range of ionizing alpha and beta particles, and gamma and x-rays that may be emitting harmful levels of radiation. Many detectors sense ionizing radiation with an enclosed Geiger-Mueller (G-M) tube to count radiation particles or rays. Alpha and beta particles are measured in counts per minute (CPM) or counts per second (CPS). Gamma rays and x-rays are measured in milliRoentgens (mR) per hour, microSieverts (μSv) per hour, or milliSieverts (mSv) per hour. Alpha particles are positively charged and heavier than beta particles, and have a limited range of approximately 3 to 5 centimeters by air. Alpha particles can be shielded by objects such as paper and unopened skin. High-energy beta particles are electrons, heavier than gamma rays, and can take either a positive or negative charge. Beta particles can be shielded by aluminum or wood. High-frequency (short wavelength) gamma rays are the strongest and lightest rays. Gamma rays are more penetrating than alpha and beta particles. They can be shielded by dense materials such as lead, and large masses of concrete, hardened steel, or water. X-rays are man-made gamma rays, and have essentially the same properties and function. Radiation detectors commonly have either an analog or a digital display. Analog radiation detectors output with a needle-point scale, and digital units generate a numerical LCD digit display. Radiation detectors are commonly used by hobbyists for safety detection and rock inspection, and professionals in the in the nuclear, medical, mining, instructional, and research industries.

I ordered one of these and happy with the design, but the GM tube died just outside of the 30-day warranty period (counter always shows zero/no activity now). International Medcom support was helpful - but the tube is the most expensive component in the package.

Apparently, GM tubes losing their gas is not uncommon. I was unable to find information on average failure rates/stddev/etc, so be warned that it may last quite a while, or die quickly like mine (it was kept in an office, and never used in a harsh environment - only used a few times total).

The GM tube is an LND3717 (a high quality tube). LND offers 6 month warranty on the tube itself vs. the 30 day on the Inspector Alert.

I just want to comment on the customer issue with broken geiger tube. IMI International Medcom offers the best warranty in the industry at this time: One Year on Geiger tube, 2 years on instrument. Staff at IMI has tried to contact customer with problem with no success. Please see International Medcom website for details on the warranty program.

Looking for a way to reassure myself and family, I found many reviews touting the benefits and features of this easily used, easy to comprehend, but scientifically accurate and intensely comprehensive monitoring of alpha, beta, and gamma radiation. I use it for monitoring air, precipitation, food stuffs, and this spring, my garden/greenhouse. Keep informed with enenews.com and your own monitor. Don't trust the government to tell you when things are unsafe. Become self reliant and make informed decisions with this investment in your and your children's future.
