The CMA wireless radiation sensor detects alpha, beta and gamma radiation. The radiation sensor uses a Geiger-Müller tube to detect this radiation. The sensor is equipped with an OLED colour display that shows sensor information and the measured values. This makes the sensor suitable for use as a stand-alone measuring instrument.
This wireless radiation sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programmes/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
To detect radiation, point the radiation sensor towards the radiation source. To detect alpha radiation, place the sensor close to the source, as alpha particles do not travel far through the air.
The radiation sensor comes factory calibrated in counts per minute (cpm).
Technical specifications:
-Measuring range: 0 .. 20,000 counts per minute (cpm)
-Resolution: 1 count per minute (cpm)
-Warranty: 36 months
-Type of radiation: alpha, beta and gamma radiation
-OLED display: 0.96" 128 x 64px
-Min. dead time 90 μs
-Audio output: Click sound for each count
-Maximum sample frequency: 1 Hz
-Battery life: 6 hours when fully charged (rechargeable)
-Connection: Bluetooth 5, Low Energy (Mac, Android, iOS) Bluetooth 2.1, Classic (Windows) or USB-C 2.0
-All sensor specifications can be found in the Manual, see Downloads.
Suggestions for physics and radiation practicals:
-Monitoring of background radiation: measure the natural background radiation from cosmic rays, earth minerals and materials.
-Monitoring of radiation from common radioactive materials: use everyday radioactive materials such as potassium salts or lantern mantles to demonstrate the random nature of radiation
-Determination of radioactive decay and half-life: measure decay rates and half-lives using isotope generators such as protactinium (72 s) or Ba-137m (153 s)
-Radiation level versus shielding: record radiation levels with different thicknesses and types of absorbent materials – aluminium for beta, lead for gamma – and compare their half-thickness for alpha, beta and gamma radiation
-Radiation intensity versus distance: measure how radiation levels change as the sensor is moved further away from the source
