Electromagnetic Radiation

Gamma rays from uranium-238: * 0,013 000 MeV energy and 0,088 313 probability * 0,066 376 MeV energy and 0,000 970 probability

X-rays have the highest frequency in the electromagnetic spectrum.

Living under a cell tower base station is generally considered more dangerous than living near one. Radiation exposure decreases significantly with distance, so living directly under the tower would expose you to higher levels of electromagnetic radiation. It's always advisable to maintain a safe distance from cell towers to minimize exposure risks.

Background radiation is the term used to describe the low levels of ionizing radiation that are constantly present in the environment from both natural and man-made sources.

A dosimeter based on sensitized film is one kind of radiation dosimeter, but there are other different kinds, and film badges are becoming less common.

One widely known dosimeter is the direct read "pen style" electroscope dosimeter. Another "pen style" dosimeter is a miniature ionization chamber, but like the film badge dosimeter requires special equipment to read it later in a lab.

Probably the most commonly used type of dosimeter outside of emergency response is the TLD, or thermoluminescent dosimeter.

The basis for all telecommunications signals is the transmission of data through electronic or optical signals. These signals carry information such as voice, video, or text over different mediums like cables, airwaves, or fiber optics. The signals are encoded and decoded using specific protocols to ensure accurate and secure communication.

No, ultraviolet light has a higher frequency than visible light. Visible light has wavelengths between about 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.

Night sights, such as night vision goggles, typically use the infrared band of the electromagnetic spectrum. Infrared light is emitted by warm objects and can be detected by night vision devices to create nighttime images.

Infrared radiation is responsible for producing the warmth feelings in a campfire. This type of electromagnetic radiation has longer wavelengths than visible light and is emitted by the hot materials in the fire, transferring heat to our bodies and causing the sensation of warmth.

Yes, although probably not the kind you're thinking about. Microwaves use electromagnetic radiation to heat food. If the microwave is properly constructed and not damaged, none of that radiation escapes.

X-rays are a type of electromagnetic radiation commonly used in medical imaging, such as X-ray radiography, computed tomography (CT), and fluoroscopy. This form of imaging allows healthcare professionals to visualize internal structures of the body to aid in diagnosis and treatment planning.

The ozone layer in the stratosphere absorbs harmful ultraviolet (UV) radiation from the sun. This layer acts as a shield, preventing most of the UV radiation from reaching the Earth's surface, where it can cause harm to living organisms, including humans.

Exposure to radiation can potentially affect the magnetic properties of a magnet by altering the alignment of its magnetic domains. The level of impact would depend on the type and intensity of the radiation. In general, low levels of radiation may have minimal effects, while high levels can cause demagnetization or changes in magnetic strength.

IR, visible, UV.

Our sun's radiation peaks in the yellow portion of the spectrum.

Visible light is found in the middle of the electromagnetic spectrum between ultraviolet and infrared light. It has wavelengths ranging from around 400 to 700 nanometers and includes the colors we can see with our eyes, such as red, orange, yellow, green, blue, indigo, and violet.

If the gamma rays and X-rays have the same frequency, the electron will have the same energy regardless of which type of radiation is interacting with it. The energy of the electron is determined by the frequency of the radiation it absorbs, not the type of radiation.

Bluetooth is a wireless interface standard for exchanging data over short distances (using UHF radio waves in the ISM band from 2.4 GHz to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). It can transmit many kinds of data: digitized audio, text, mouse pointer movements, etc.

by applying a voltage across the boundary of two semi-conductors electrons are forces to travel across the boundary. This boundary has a voltage drop and the electrons are required to lose a discrete amount of energy in crossing it. In the case of the light emitting diode, it is a energy in the range of visible light.

Radio waves have wavelengths that can vary from hundreds of meters to as small as a few millimeters. For a typical adult human, who is around 1.7 meters tall, the closest match in terms of wavelength would likely be in the lower frequency range of radio waves, such as Medium Frequency (MF) or Long Wave (LW) radio waves.

Electromagnetic radiation is made up of electric and magnetic fields oscillating together in the form of waves. These waves can vary in frequency and wavelength, giving rise to different types of electromagnetic radiation such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

You can make electromagnets out of it. You can make magnetic shielding out of it, for rapidly changing magnetic fields. You can store energy in its field. You can use it to make transformers and motors.

The only part of the electromagnetic spectrum that we can see is the small yet significant part of visible light. Visible light is not harmful for humans, but some of the other types of waves are.
