Russian scientists developed and patented a unique detector for ultraviolet radiation, which allows accurate measuring of received dose in any range of this dangerous radiation.
      
      Heart of this device is so-called Z-sensor, a receiver, sensitive to ultraviolet radiation. This sensor facilitates recognition and integration of UV radiation in a simple way – UV changes semiconductor structure of the sensor, and amount of change depends on both radiation intensity and exposure time.
      
      Conduction meter is scaled to measure total radiation dosage during given time period. The device also has a beeper, which warns users about a radiation source located nearby, and measures radiation in various UV ranges.
