talks about research into pulsars, which are spinning neutron stars which emit beams of x-rays and radio waves from the star's magnetic pole, and states astronomers discovered increased brightness or dimness of ...
Based on X-ray, visual and radio observations of the large flare of 16 May 1981, it can be concluded that a large flare is a long duration energy release process, and it can be interpreted as a sum of smaller flares throughout the active region. It can be accompanied by X-ray and ...
X-rays and CT scans both use a small dose of ionizing radiation to produce images. An MRI scan, however, doesn’t work this way. It uses powerful magnets and radio waves to create the images instead of ionizing radiation. So, you are not exposed to radiation when you have an MRI scan...
X-rays are a form of electromagnetic radiation, on a spectrum (频谱) that runs from radio waves on the low end to gamma rays on the high end and includes visible light, too. Scientists don’t know why lightning spawns X-rays. They theorize it involves a "runaway breakdown" of the air...
As long as the difference between the viewing angle and the jet angle is maintained, a continuous range of jet angles can be found that is consistent with the observations in X-rays and at radio wavelengths, mostly covering the peak. Dashed lines show light curves computed using the semi-...
X-rays and Gamma Rays are high frequency electromagnetic radiation:Energy and IonizationGamma rays, X-rays, and some ultraviolet waves have such high energy that they are ionizing, meaning they can knock electrons out of atoms.This makes atoms charged and more likely to form new chemical ...
Radio Waves and Visible light are referred to as non-ionizing. Digital Dental X-Rays Digital x-rays produce a significantly lower level of radiation compared to traditional dental x-rays. In addition to being faster and more comfortable to you, because the digital image is captured electronically...

As energetic electrons under the circumstances emit both X-rays by the bremsstrahlung mechanism and radio waves by the gyrosynchrotron mechanism simultaneously, it is shown that the radio flux density is closely related to the X-ray flux density. Solving an integral equation describing the X-ray ...
