RADEX RD1212 Geiger Counter is the newest model from Radex.

This one is for The People:

    EASY to understand

           SIMPLE to use

                 And it's a whole lot of Fun too!

Comes with a USB-to-PC cable and RadexRead Software.

RadexRead allows you to perform the following functions:
• view measurement results stored in memory
• save results in TXT and CSV formats
• delete measurement results from the device memory
• assign readings to map locations  new!
• view other readings on same map  new!

Incredibly Fast (just 10 sec), very accurate 
and as far as the features go, this one outclasses them all:  

  • Gamma, Beta and X-rays radiation detection
  • 10 sec. measurement cycle
  • Detection range: 0.05~999.0 mcSv/hr
  • ±15% accuracy
  • 999.0 µSv/h upper threshold
  • stores measurement results in memory
  • data transfer to PC
  • self-testing
  • Time and Date functions
  • audible alarm
  • vibration alarm
  • integrated flashlight
  • multilingual (Eng, De, Fr, Rus, Jp)
  • Requires 2 x AAA batteries (included).
  • One year Manufacturer's Warranty included (all warranty claims are processed by authorized resellers only).

RD1212 can register and display the value of a dose-rate as high as 999.0 µSv/h.

When presence of a strong radiation source is detected, measurement period drops from 10 seconds to as low as 1 second, to provide real-time accurate radiation read out.

Most other features from the RADEX family were also retained, i.e. the usual frame with a large LCD screen, three buttons operation, battery charge indicator, display backlighting and personal settings like threshold alarm activation, alarm signal strength, and backlight option.

You can familiarize yourself with the RD1212 device operation by reading the "Operation Manual".

* 1) Measurement Cycle decreases when the ambient radiation exceeds 3.0 µSv/h.
   2) The more Measurement Cycles conducted the greater the reliability of indications.

** 1) Using factory settings, with ambient radiation below 0.3 µSv/h and two "AAA" batteries with a capacity of 1350 mAh.
     2) The device can operate with one power element «ААА» type (the time of continuous operation will be reduced).

Not all radiation is the same, so scientists use the ‘sievert’ to measure the health risks of radiation.

SAFE Radiation Dose: 0.09 microsieverts
Exposure: One year living within 50 miles of a nuclear power plant
