Product Description
The Radiation Alert Inspector Xtreme 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 additional functions, and comes with a protective rubber boot. This radiation detector has the ability to 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 Xtreme 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 beeping 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 (G-M) 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. It comes with a protective rubber boot with access to an operational panel. The Inspector Extreme has a one-year, limited warranty for materials and craftsmanship, and a 90-day warranty on the GM tube.

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.

Also tested an old computer monitor (CRT type) that was giving my friend lots of headaches, it was putting out 5.49 milliGauss, about as much if you were to put your face right in front of a microwave oven. Mmm toasty, now wonder her eyes were burning and her forehead was hot. p.s. hope her boss buys her an LCD monitor, not so much radiation. 21 of 24 people found the following review helpful: Happy with purchase!, By GlobalJoe "GlobalJoe" (Pearl River NY) - See all my reviews Amazon Verified Purchase This review is from: Lutron 822-A Fully Digital EMF Meter (Wide Range, High Resolution) (Electronics) I am very happy with my purchase of the Lutron EMF meter. It is easy to use and accurate. I used it simultaneously with the K-2 meter and side by side they both worked well and together they confirmed the EMF readers throughout the areas that I examined. |

Davis Instruments Vantage Pro2 Weather Station (Wireless) Reviews
| 49 of 49 people found the following review helpful: How Serious Are You About Your Weather?, By 27 of 27 people found the following review helpful: Very satisfied, One worry I had was how well the sending unit would work in the winter when there is relatively low and short light to charge the battery. I have had no trouble at all after several years. One thing is that the signal tends to get a bit weaker on batteries, so at the extremes of range, I sometimes loose the signal overnight. At more reasonable ranges, all is very well. By the way, I first got the integrated sensor suite and plugged the anemometer into it. It worked fine. A year (or so) ago, I sprung for the separate anemometer transmitter and mounted it up above the peak of the roof. All continues to be fine with just a little tweaking of the settings in the main... Read more 20 of 20 people found the following review helpful:  Chronic Instrument failure, By Since it was within the one year warranty, they finally replaced it after a lot of calls. Shortly after the warranty expired, the outdoor temp/humidity sensor failed. ( $125 to replace it ) , a little later the wind direction indicator failed. Have not replaced it yet. ($175 to replace it ). Jury is out on this one. E-mail support is non-existent. They will never reply to any of your e-mails. Customer support is also weak. The Davis weather stations used to be fine instruments. My 1st one lasted a little over five years before it failed. I am very disappointed with Davis. Now looking for another brand to switch to. Open to any suggestions as to what brand to try. |
