4K Radon 220 in a diffusion cloud chamber

Some Radon 220 decaying in the cloud chamber (at +1 min). The visible area of the detector is 40 cm x 20 cm. A magnet in the right area produce a magnetic field which deflect natural electrons and positons. Recorded with a Panasonic X1500 3840x2160 25p 1/25s F/3 Gain 5dB. I recommend to push the luminosity of your screen to the maximum. www.cloudylabs.fr
