Get a geiger counter.
You can still buy a surplus geiger counter pretty cheap these days too actually.
There are 2 or 3 available nothing is cheaper than 200.
They have been checked out and tested here at our licensed radiological calibration laboratory.
Requires 1 or 2 regular d cell batteries.
Operates from one 9v battery not included.
It works with most common geiger müller tubes and easily connects to radiation rate meters data loggers true random number generators and the radiation network s geigergraph software.
Rwizard about 9 years ago 1 i m one of the folks who were lucky enough to get one of these before they sold out.
I ve interfaced mine to an 18f2520 and an lcd.
The tube is mounted with cable clamps over a hole in the bottom of the box covered by a perforated aluminum shield.
The holes in the perforated aluminum directly below the tube were drilled to a larger diameter to block less radiation.
This diy geiger counter clicks and flashes an led each time it detects a radioactive particle.
This drop in price for the device along with modern technologies have made geiger counters more accessible today than ever before.
You can also buy a pocket geiger counter from good ol waldo s world of chinese imports for about 175.
As the power consumption went through the roof when i tried this the lt700.
This tiny fully assembled geiger counter is only 1 89 long x 0 86 wide x 0 46 thick.

Share your radiation readings with the whole world.
They mount securely on the side of the cd v 700 and plug into the standard headphone jack.
These are new in the box external speakers specifically and originally made for the cd v 700 series geiger counters.
