There are several types of machines used to measure radiation. The 'classic' is the Geiger Counter which dates back to the late 40's or 50's. It's quite efficient, especially in measuring α and ß Emissions and passably so on Γ Rays. It works by counting the electric arc discharges inside the counter sensing probe caused by impinging radioactive particles.
Slightly newer, is the Scintillation Counter which is far more accurate in Γ Ray work. The Scintillation Counter, in spite of it's impressive name is really a rather simple instrument. They are comprised of a Photoelectric coupled with a Crystal that emits a tiny flash of light when it is exposed to Γ Rays ... the stronger the Γ field, the more the flashes.
Those are 2 basic types of Radiation Monitors. The designs cited above are the 2 prototypical flavors.

What types of radiation should you be worried about?
The most dangerous type of radiation is Nuclear radiation which is the one that should be most worried about.
What are the some uses of nuclear radiation?
energy/electricity/weapons
What do you mean by nuclear accidents and can you explain two basic types of nuclear weapons?
A nuclear accident is the unintended release of nuclear radiation into the environment, such as damage to a nuclear reactor or to a nuclear weapon (plane crash carrying nuclear bombs, etc). The two basic forms of nuclear weapons are fission and fusion weapons.
What can one do to protect oneself from background radiation?
Background radiation come from black body radiation which is mostly infrared and microwave. Background radiation is not harmful at all. Fear from background radiation come from confusion of the word radiation where we mostly concern nuclear radiation, but light is also a form of radiation and we live within the bright day light on a normal basis.
Why could a room heated by a coal fire feel uncomfortably draughty?
coal gives off nuclear radiation
What is a Geiger counters used for?
It is used to measure radiation and is commonly used to detect objects that produce nuclear radiation.
What do they use to measure nuclear radiation?
Nuclear radiation is measured using instruments like Geiger counters or scintillation detectors that detect the presence and intensity of ionizing radiation. These devices can detect various types of radiation, including alpha, beta, gamma, and neutron radiation. Measurements are typically reported in units such as sieverts or rem, which quantify the biological effects of radiation exposure.
How long does the lethal radiation from a nuclear bomb take to die?
That depends on the initial amount and type. It also depends on altitude (or depth) of burst. If you know the isotopes involved you can look up their half lives, measure current radiation intensity, and calculate time until radiation will drop to desired level. You can also periodically measure radiation intensity over a period of time, then extrapolate to get a reasonable estimate of time to drop to desired level without knowing isotopes.
What a geiger counter used for?
It is used to measure radiation and is commonly used to detect objects that produce nuclear radiation.
What are the signs of nuclear radiation?
There are no immediate signed of nuclear radiation.
What does a Nuclear radiation device measure?
A nuclear radiation device measures the level of radiation present in a particular environment. It can detect and quantify different types of ionizing radiation, such as alpha, beta, gamma, and neutron radiation. These devices are essential for monitoring radiation levels in areas like nuclear power plants, medical facilities, and environmental sites.
What are the two devices that are used to detect nuclear radiation?
The two devices used to detect nuclear radiation are Geiger-Muller counters and scintillation detectors. Geiger-Muller counters measure ionizing radiation levels, while scintillation detectors use crystals to detect radiation and convert it into light pulses for measurement.
What type of radiation do nuclear weapons emit?
Nuclear weapons emit various types of radiation, including gamma radiation, neutron radiation, and thermal radiation. These forms of radiation can have harmful effects on living organisms and the environment.
How radiation affected by surface temperature?
Nuclear radiation is not affected at all, but radiation by Electromagnetic Radiation is. This is a straight Physics topic, not Nuclear Energy.
How does distance affect intensity of radiation?
The intensity of radiation decreases with distance following an inverse square law. This means that as you move farther away from the radiation source, the intensity decreases exponentially. Therefore, the closer you are to the source, the higher the radiation intensity you will experience.
Is there gamma radiation in nuclear bombs?
Yes, nuclear bombs produce gamma radiation as a result of the nuclear fission or fusion reactions that release high-energy photons. Gamma radiation is a form of electromagnetic radiation that accompanies the explosion of nuclear devices.
What is radiation rays?
Radiation rays are forms of energy that travel through space in the form of electromagnetic waves or particles. They can be natural, such as sunlight or cosmic rays, or man-made, like X-rays or radiation from nuclear reactions. Depending on the type and intensity, radiation rays can have various effects on living organisms and materials.
