Sensor *,The radiation sensor BT70i detects alpha beta and gamma ionizing radiation. The sensor outputs a pulse when decay is detected. Also a clicking sound is emitted and a LED light flashes. The sensor is suitable to detect low level radiation emitted by e.g. potassium fertilizers or gas lantern mantles. Range: 0 ... 1000 cps (counts per second) Can be used to: - monitor background radiation - record radioactive decay and determine half life - investigate radiation versus shielding.
