This video focused on detecting sensitivity on any radiation, not the accuracy and feature comparing. Most of us have only limited knowledge about the radiation, and we only need a sensitive device to answer "Yes" or "No" on all kind of radiation. The GMC-600Plus has large pancake sensor, which can capture more radiation than a smaller sensor, and it has ability to detect Alpha, Beta, and Gamma radiations, whereas the RadiaCode only detects Gamma radiation.
In reality, all natural radiation includes Alpha, Beta, and Gamma components. However, if you need to analyze Gamma rays energy exclusively, the RadiaCode Spectrometer feature will be a good one.
The video tested sensitivity on three market popular radiation detectors: RadiaCode, Radex and GMC-600 Plus . The testing sources can be obtained easily from the market: salt substitute, Geiger Counter Test Card and a AM-241 from smoke detector.
The first testing source is a salt substitute. The salt substitute was purchased from a local grocery store, and it contains potassium
chloride which releases a small amount of gamma radiation.
The Radex is not able to detect such small amounts of gamma rays.
The radiaCode does not detect any radiation from it either.
The GMC-600 Plus detects some gamma radiation from it. It seems to be about 0.6 microsieverts per hour at most.
The second testing source is a Geiger Counter Test card. The test card is made from a natural uranium ore. It contains a low level of radiation which is detectable using a Geiger Counter. The Radex detects the radiation at a level of about 10 microsieverts per hour.
The radiaCode detects the radiation level at 0.84 microsieverts per hour at its peak.
The GMC-600 Plus detects about 36 microsieverts per hour at its peak.
The third testing source is from a smoke detector sensor. It has a small amount of the Americium-241 isotope.
The Radex detects radiation at a level of about 1 microsievert per hour.
The radiaCode detects the radiation level at 2 microsieverts per hour at most.
The GMC-600 Plus detects radiation from it at about 130 microsieverts per hour at its peak.
From the test, it's clear that the quickest and most sensitive device out of these three is the GMC-600 Plus Geiger Counter.
