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.
