ALL OUR ITEMS ARE IN AUCKLAND – READY FOR FAST SHIPPING.

The natural environment in which we live has a certain amount of radiation, real-time data will fluctuate within a certain range. Use of nuclear radiation detector helps to avoid radiation hazards.

You Tube instruction and use video here. Shows and explains Alpha and Beta testing.

To measure beta-rays emission you can remove the rear part of the case to bring the sensor (Geiger-Muller counter, GM-counter) close to a source of radiation.

With this detector, BR-6, it may be difficult to measure beta-rays due to big case, so you can open the case and contact the counter bulb with an object for different method and possible higher accuracy.

For higher sensitivity, you can also take off the heat shrink plastic over the tube.

An Instruction manual here.

Review and test of the Chinese BR-6B Geiger counter, which is now turning up online for less than £100, for that price it is a very good investment however it does have a limitation that it maxes out at 99.99 microsieverts which is a fairly low number for a Geiger counter, however if you are using it for low level readings this is totally fine.

Features:
High sensitivity, wide measuring range, has a long service life.
Use of sophisticated G-M Geiger-Muller tube as the core sensor.
Can be applied to material inspection, environmental test, radiology protection, radiopharmaceutical screening, etc.
Compact and portable, the operation interface is simple and clear, easy to use.

The ionising effect of radiation is used in the Geiger-Muller (GM) tube as a means of detecting the radiation. The GM tube is a hollow cylinder filled with a gas at low pressure. When alpha, beta or gamma radiation enters the tube it produces ions in the gas. The ions created in the gas enable the tube to conduct.
