Radioactivity

Geigermätare är ett instrument som kan mäta radioaktivitet.

Detection instrument for observing scintillations produced by radioactive decay. When a radiation cartridge (226Ra, 4 kBq, U8483115) is screwed into the instrument so that its radiation outlet is directed downwards onto the exposed zinc sulphide screen, it is possible to look through the eyepiece of the instrument in total darkness and observe the random light […]

Self-quenching halogen pulse ionisation chamber for detecting alpha, beta, gamma and x-ray radiation. In metal housing with mica window, removable mounting clamp with shaft. Long plateau length. Filling: Neon/argon mixture, halogen as quenching agent Cathode dimensions: approx. 39×14 mm² Window: mica, 9 mm dia. Mass per unit area: 1.5 – 2.0 mg/cm² Plateau length: 400 […]

Expansion cloud chamber for observing the paths of α-rays. Cover and sidewall are of plexiglas.  By compressing the attached rubber ball and then allowing it to expand, a supersaturated isopropanol-water mixture is produced in the cloud chamber. Following that, the paths of the α-rays revealed by droplet formation are visible for 1 – 2 seconds […]

Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off and power supplies for direct connection to light barriers (U11365) or a Geiger-Müller counter (U8533430). For event counting, a fixed counting period […]
