The article provides information about energy radiation. It is a stream of energy carried by very small particles that travel at high speeds. Some these particles are charged particles, uncharged particles, and photons. Alpha particles are the heaviest, weighing about seven million billion billion...
WHAT IS RADIATION? Radiation is the process by which energy is emitted as either particles or waves. Broadly, it can take the form of sound, heat, or light. However, most people generally use it to refer to radiation from electromagnetic waves, ranging from radio waves, though the visible ...
Atmospheric radiation is radiation that passes through the Earth's atmosphere and might circulate within it. Not all of the energy from the sun actually reaches the Earth's surface, and that which does might change in behavior by moving through the atmosphere. Researchers study atmospheric radiation...
Because they are radioactive, radon and radon progeny emit alpha particles, a high-energy radiation that damages DNA in human cells and causes lung cancer. When radon is inhaled, particles become lodged in the lungs where they continue to emit alpha particles. ...
The largest source of ionizing radiation for the average American is from naturally occurring radon in the air. Without heat from naturally occurring radioactivity, the Earth’s core would have frozen billions of years ago. DOE Office of Science: Radioactivity Contributions ...
Non-ionizing radiation is a category of radiation that does not have enough energy to ionize molecules or atoms. This inability is due to the low frequency and high wavelength of radiation waves. Radio waves, infrared, microwave, visible light and near ultraviolet are the only forms of this ty...
1、什么是同步辐射光源?What is a synchrotron radiation light source? " Synchrotron radiation" refers to a continuous band of electromagnetic spectrum including infrared, visible light, ultraviolet, and X-rays. This light has been called "synchrotron radiation", since it was accidentally discovered in...
The Nuclear Regulatory Commission (NRC) is the federal agency responsible for implementing EPA's radiation exposure standards through regulation of nuclear power reactors and many other uses of radiation. The Department of Energy (DOE) also implements these standards at facilities under their supervision...
(gigahertz) of cycles per second. In a radio wave, thewavelengthis inversely proportional to the frequency. Radio frequencies are not visible to the human eye. As the frequency is increased beyond that of the RF spectrum, electromagnetic energy takes the form of microwaves, infrared radiation (...
