there will be someone to blame for not getting info out to public in an orderly fashion, guess us nobody's will have to take over where the NEWS and GOVT. left off and chose not to continue!
Ever feel that TPTB would rather show lame shït on the news all the time , than show anything on Afghanistan, fukushima or anyhting of importance,?
Lot's of shït going on in the world everyday and the news doesn't ever catch or show any of it here in the USA!
No wonder the world treats us like dummies!

The quality of leadership (or lack thereof) gives the US the dummy effect.

I hope the food importation from Japan following Fukushima, as allowed by Sec of State Clinton, is enough of an issue to disqualify her from any Presidential aspirations.

There's plenty of room for all God's creatures. Right next to the mashed potatoes!

the world treats us like dummies because we are.

Does anyone have any personal opinion on a good geiger counter?

In the March, 2013, issue of “Nuts and Volts” magazine is an article describing a homemade radiation meter. As of this writing a complete kit is available to construct this device from http://www.nutsvolts.com. This device features a voltage output that can be continuously logged onto a PC with software which uses a $29 Dataq voltage data logger that connects to the PCs USB port. The device contains a built in timer capable of counting seconds, minutes, hours, or days and a LCD display. One may select the time interval for recording radiation by means of a momentary switch. An audible alarm is given if the radiation rate exceeds 30 uR/hr. An alkaline 9 V battery will last about two days with continuous use. The unit is mounted in a small plastic Serpac case, which has a built in holder for the 9 V battery. This is not a kit for the beginner. I had trouble identifying which transistor was which. The circuit board has tiny traces. Two capacitors were missing.

A very interesting and useful rate meter is the RADAlert, small enough to fit on one’s key ring. Available from some vendors listed at the http://www.ki4u.com site. We keep one of these in the glove compartments of our vehicles. This detector does not use a Geiger-Muller tube. Rather there is a compound inside that produces a small flash of light when struck by a gamma photon. This flash of light strikes a cadmium sulfide photocell, which produces a small voltage spike that is processed in a way that the number of chirps emitted by the RADAlert reflects the amount of radiation. This detector arrangement is not easily saturated. At 50 (and above) R/hr 10 chirps will be heard every thirty seconds. The number of chirps decreases with decreasing radiation rate measured so that if the radiation is 0.1 R/hr only one chirp is heard every thirty seconds. The internal battery is said to be good for about 10 years. One may test the device by chilling and then returning to room temperature. This process produces chirping until the innards of the device all reach ambient temperature. Note that the upper reading this device will properly measure is 1/10 that of the CD meters and 1000 times that of the M4 meter discussed above. The RADAlert does not respond to alpha or beta particles, but I do not consider this limitation of any real importance. The great thing is that this device is constantly on.

This is by no means an exhaustive list of available rate meters. For example, http://www.readymaderesources.com has a number of rate meters for sale.

Post your results wave.gif

This is the one I have,,,used to be cheaper,,,

think it is about 13 years old,,,still working,,,

clicking on background radiation,,,does Alpha,,,Beta,,,and Gamma,,,

the sensitivity on beta is very good,,,if you research this stuff...

Sensitivity

Alpha above 3.0 MeV
Beta above 50 KeV
Gamma above 7 KeV


The geiger tube comes with a black boot to protect the thin mica end window. This boot needs to be removed to detect alpha particles. However, gamma and beta particles will pass through the boot and be detected.

The United States has declared that this product for restricted exporting to foreign countries. It may still be possible, but will require additional information prior to shipping.

I have the one with the wand,,,used to be 150 dollars kit,,,

GCA-02 Analog Geiger Counters

http://www.imagesco.com/geiger/geiger-counter.html

This Geiger counter outputs audible click and will blink a LED with each radioactive particle it detects. In addition it has two digital outputs that may be connected to a number of accessory instruments; a data logger, Digital Meter adaptor that outputs an approximate radiation level, RS-232 adaptor to plot radioactivity on a PC.

so,,,guess the gas hasn't leaked out of mine yet,,,13 years...

yay.gif

if you do the kit,,,you need to know a little about electronics,,,

and need to set the high voltage supply just right,,,so you get the

sensitivity without arcing the tube...otherwise get the assembled...

Geiger Counter Technical Data


Radiation Detected
Alpha, Beta, X-Rays and Gamma.

Radiation Detector
LND 712 Geiger-Muller Tube: Ne + Halogen filled. GM Tube has a .38" effective diameter with a 1.5-2.0 mg/cm2 mica end window.
Resolution of the LND 712 GM tube is 0.05 mR/hr.

Detector Sensitivity
. Alpha above 3.0 MeV
. Beta above 50 KeV
. Gamma above 7 KeV

Countable Pulse Resolution & Range 1 Count Per Minute (CPM) - 5000 Counts Per Second (CPS)

Radiation Resolution: (Imperial).05 mR/hr
Radiation Range: (Imperial) Background Radiation* 18-22 uR/hr - 1000 mR/hr
Radiation Resolution: (Metric).0005 mSv/hr
Radiation Range: (Metric) Background Radiation* 0.18-0.22 uSv/hr - 10.0 mSv/hr

*Background Radiation in our location on average varies between 18-22 uR/hr Imperial (0.18-0.22 uSv/hr Metric). Your background radiation may be different due to your location and elevation on the planet.

The GCA-02 is sensitive enough to detect background radiation as well as NORM (Naturally Ocurring Radioactive Materials) and TENORM (Technologically Enhanced Naturally Occurring Radioactive Materials) objects in your enviroment.
