This radiation detector, or Geiger Counter, is widely available under a range of different brand names and prices. This one cost me £48 but I have seen identical models priced from £43 to well over £100. Most of them are exactly the same but I have seen a few variants out there with built-in rechargeable batteries and kickstand.

For those that need to know, here are the key technical specifications for this device:

Specifications
Model BR-6 v3
Size: 135 x 70 x 40 mm
Weight: 169g
Material: ABS
Power x2 AA Batteries/ USB
Energy Range: 20kev-3.0Mev≤±30%（137Cs-）
Sensitivity: 80cpm / usv / (Co-60)
Test Accuracy: 0.01μsv / h
Time Range: 0-99.99µsv / h
Time Error: < 10%
Average Error: < 3%
Type of Detection: β γ and X Rays

Build quality is OK but being made from ABS plastic and not being waterproof will limit how you use it outdoors. One thing I do like about the design is that the casing grill takes in air from three sides hopefully allowing for a more accurate reading from the Geiger-Muller tube inside. The unit is powered by two AA batteries but it can be powered from a Micro-USB port on the side, although this does not charge the batteries inside, so unplug them when in USB mode. The manual claims the device can detect β γ and X Rays in an energy range of 20kev-3.0Mev≤±30%（137Cs- with a sensitivity of 80cpm / usv / (Co-60) - whatever that means!

The detector measures in microsieverts per hour and maxes out at 100. This is not a particularly high level but if you ever reach it then it is time to make yourself scarce. At my house in England I was getting an indoor reading of around 0.15 and around rather less outdoors. It is generally supposed that any reading below 0.52 is perfectly safe and normal.

There are three display options: Real-time, polled about once per second, an average reading for the last 8 minutes, and a graph for the same period. You can also set it to alert you when a particular radiation level is reached. The counter can be set to make the classic clicking sound or to work silently but to sound an alarm when your trigger alert level is reached.

This is a nice little budget-priced entry-level geiger counter that allows you to monitor background radiation levels quickly and easily. Shop around to find the cheapest one and I do not think you will be disappointed with it.
