Product Description

The Radiation Alert MC1K is a hand-held radiation detector that detects a high range of potentially harmful ionizing gamma and x-ray (40-100 keV) radiation with an internal Geiger Mueller (GM) tube, and has an energy-compensated sidewall for a linear reading. This dual-scale, analog meter displays counts per minute (CPM), and milliRoentgen (mR) per hour. Four selectable operational ranges, of X1, X10, X100, or X100, detect gamma rays and x-rays of ionizing radiation. The ranges can be adjusted when the meter face peaks at the highest mR level.

The MC1K model has a red, flashing counter and a beeping noise to indicate each ionizing radiation event. It has a halogen-quenched Geiger Mueller (GM) tube for sensing ionizing radiation. It checks radiation levels in the environment and objects, such as particle accelerators, x-ray shielding, and industrial gauges. An audio indicator with an internally mounted beeper can be turned off for silent operation. The MC1K cannot be returned.

Specifications

Reading Ranges Two reading ranges of 0 to 0.5, 0 to 5, or 0 to 50 milliRoentgen (mR) per hour, or 0 to 500, 0 to 5,000, or 0 to 50,000 cycles per minute (CPM).
Operational Ranges X1 in 0.05 increments 0 to 1 mR/hr or 0 to 0.01 milliSievert (mSv) per hour; X10 in 0.5 increments 0 to 10 mR/hr or 0 to 0.1 mSv per hour; X100 in 5.0 increments 0 to 100 mR/hr or 0 to 1.0 mSv per hour; X1000 in 50.0 increments 0 to 1000 mR/hr or 0 to 10.0 mSv per hour.
Accuracy Factory-calibrated by pulse generator, with accuracy + or -15% of reading full-scale, relative to Cesium 137.
Energy Sensitivity 1,000 CPM/mR/hr (Cs137). The energy response for gamma and x-rays through the detector sidewall is flat within +61% or -26% over the range of 40 keV to 100 keV, and within +35% or -17% over the range of 100 keV to 1.3 MeV.
Sidewall Detection Energy-compensated sidewall with 2 mm tin filter. 40 keV minimum through the sidewall of the detector. Energy compensation is only effective through the sidewall.
Temperature Range -20 degrees to 55 degrees C (-4 degrees to 131 degrees F) and an internal detector.
GM Tube Halogen-quenched, internal Geiger Mueller tube. The effective diameter is 0.92 cm/0.36”.
Dimensions Dimensions are 209 mm x 71 mm x 50 mm (8.2” x 2.8” x 1.9”).
Weight 235.7 g (8.3 oz).
Output 3.5 mm headphone jack for use with observer software (not included) and Windows-based computers.
Normal Background Radiation Approximately 4 CPM.
Battery 9-V alkaline battery (not included) for approximately 2,000 hours of continuous use in a normal background.

Radiation detectors can detect a broad range of ionizing alpha and beta particles, and gamma and x-rays that may be emitting harmful levels of radiation. They sense ionizing radiation with an enclosed Geiger Mueller (GM) 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.

SE International manufactures radiation detection products and accessories under the Radiation Alert brand. The company was founded in 1979 and is headquartered in Summertown, TN.

2 of 2 people found the following review helpful By Concerned Citizen on October 31, 2013
This detector has the same form factor as the other analog Monitor 4 (and Monitor 4EC) Geiger counters made by S.E. International. The difference is in the tube and the operating range. The tube is energy compensated, much like the Monitor 4EC, but with a higher range of 1000 mR/hr. They might have called it the MEC1000 or M4EC1000 or MEC1000 or something to make that "clearer".

You might be wondering what "energy compensated" means in relation to a GM tube. The EC tubes are more linear in their response to gamma radiation. (WHAT?!?! you say) This means that if an isotope gives off an energy of 60KeV or 200KeV, the meter will response "linearly". That is to say that you will get a one to one count, regardless of the energy. If the tube was uncompensated, like in the Monitor 4, the tube might over respond depending on the energy being given off by the isotope.
