Consumer Geiger Counter

meters

• pancake tube - 2 inch GM pancake tube
• thin mica Alpha window

Potassium-rich food that have natural occurring radiation from Potassium 40 found in dried bananas chips and salt substitutes. That radiation presence can be detected with the Inspector Alert and Onyx meters. Do a time test for 12 hours of detection.

Nai Scintillation Crystal versus Geiger Mueller Tube

This needs to be verified, info from source selling Nai Scintillation Crystal type detectors. Are they really better?

Geiger Mueller Tube based meters are affordable but only limited in usefulness. Better than nothing! Source says not useful.

GM (Geiger Mueller) based Geiger counters will usually be inadequate for detection of radiation in food and water.

G Explorer Nai Crystal is much better also very expensive.

To locate and identify if there is radiation in food, measurement is best performed by super sensitive Nai scintillation crystal radiation monitor.

about radiation

There are four primary types of ionizing radiation – alpha, beta and gamma radiation as well as x-radiation (x-rays).

alpha particle can travel no more than one to three inches in the air before stopping, and can be stopped by a piece of paper. However, they can pass through a thin mica window. mica is very important in radiation measurements.

Beta particles can damage skin, however, both alpha and beta radiation are most harmful when inhaled or ingested.
