Geiger Counter - Ionizing Radiation Tester - Dosimeter - FNIRSI-GC01

The Fnirsi brand product is an ionizing radiation counter used to detect nuclear radiation. The dosimeter detects beta, gamma and X-RAY radiation. The meter has a USB-C connector so it can be charged using a phone charger.

An ionizing radiation detector (also known as a dosimeter or Geiger counter) is a device used to measure the dose of ionizing radiation, i.e. the amount of energy that is absorbed by an organism or material during exposure to radiation. Dosimeters are used in many areas, including the nuclear industry, radiation medicine, space research and environmental protection. The detector is made of a metal pipe located inside a glass cylinder filled with gas. It is able to detect three types of radiation: X-rays (X-rays), Y-rays and β-rays.

The basic parameters of the detector are the measurement range, which is from 0.00 to 1000 µSv/h (10 mSv/h) and the measured energy range, which is from 48 keV to 1.5 Mev with an accuracy of ±30%. Detector sensitivity is 80 CPM/µSv for Co-60. The user can view data in a variety of measurement units, including μSv/h, μGy/h, mR/h, cps, and cpm.

The radiation detector can be used in a variety of environments. It has the ability to generate an alarm when a set threshold is exceeded using an LED, vibration or sound. It is equipped with an LCD display and is powered by a 1200 mAh rechargeable battery, which ensures an operating time of up to 60 days. The detector can be charged via a USB connector. Its construction is durable and resistant to damage.
