Radiation Detection

1.What is radiation? Radiation is remission of energy as electromagnetic waves or as moving subatomic particles. 2.What is radiation detection? Radiation detection is the ability to detect and measure the radiation of interest in the presence of noise and signals caused by other radiation.

3.How do you detect radiation? You cannot detect radiation using any of your senses. So in order to detect radiation you need equipment. 4.Name different types of radiation Different types of radiation are radio, microwave, visible, ultraviolet, x-ray,and gamma rays. **__Radio radiation__** is an electromagnetic wave with a wave length between 0.5cm and 30,000m. **__Microwave radiation__** is electromagnetic radiation with lengths as long as one meter to as short as one millimeter. **__Visible radiation__** is radiation that can produce a visual. **__Ultraviolet radiation__** is wave lengths shorter than light but longer than x-rays. **__X-ray radiation__** is similar to light but of shorter wavelength and capable of penetrating solids. **__Gamma rays__** is wavelengths that are generally in the range 1 ✕ 10-10 to 2 ✕ 10-13 meters.

5. Describe most common lab instruments for detecting radiation. One common instrument to detect radiation is the **__Geiger-Muller counter__**. If the environment has a high radiation level it will beep rapidly. The Geiger-Muller will also show you the level of radiation on the screen. **__X-rays__** are another type of instrument to detect radiation. **__Scintillator__** is another detector. It is minute flashes of light which are produced by certain materials when they absorb radiation.
