Frequently Asked Questions (FAQs)
1. Can you legally buy a Geiger counter?
Yes, it is legal to buy a Geiger counter. Buying your own Geiger counter allows you to conveniently test your environment and ensure safety in your household.
2. What is the difference between a Geiger counter and a radiation detector?
While both Geiger counters and radiation detectors serve the purpose of detecting radiation, personal radiation detectors offer additional features not available in traditional Geiger counters. These lightweight instruments can detect multiple types of ionizing radiation, including alpha, beta, x-rays, and gamma.
3. Can Geiger counters detect nuclear weapons?
Geiger counters are commonly associated with nuclear weapons and fallout. While they are useful in these situations, they are also used for the detection and control of nuclear waste, by-products, and exposure in various settings such as nuclear power plants, hospitals, and mines.
4. Is 10 on a Geiger counter bad?
A reading of 10 on a Geiger counter is not necessarily bad. To cause death within hours of exposure to radiation, a very high dose of 10Gy or higher is required. Doses of 4-5Gy can lead to death within 60 days, while doses below 1.5-2Gy are not immediately lethal. However, all doses, no matter how small, carry a finite risk of cancer and other diseases.
5. What Geiger counter for nuclear fallout?
The CD V-700 Geiger counter, equipped with a Geiger-Müller tube, is commonly used for measuring low levels of gamma radiation and detecting beta radiation. It was manufactured in the 1950s and 1960s under contract to US federal civil defense agencies and is sensitive to nuclear fallout.
6. What can a Geiger counter not detect?
Geiger counters are effective in detecting low-energy gamma or X-rays. However, they cannot detect alpha or beta radiation because the charged particles do not penetrate the crystal of a Geiger counter.
7. How much radiation is safe on a Geiger counter?
In general, a range of 7-30 counts per minute (CPM) is normal in surroundings. It is considered safe if the reading on a Geiger counter stays below 150 CPM. If the value exceeds this limit, it indicates a dangerously radioactive substance or atmosphere.
