The extension of astronomy from visible light to radio waves to x-rays and gamma rays never failed to lead to the discovery of unusual objects such as radio galaxies, quasars, and pulsars.
从可见光扩展到无线电波，再到 X 射线和伽马射线，天文学总是会发现不寻常的物体，如射电星系、类星体和脉冲星。
The nuclear energy is released at the Sun’s center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength.
核能在太阳的核心被释放为高能的伽马射线。 这是一种电磁射线，就象光波和无线电波一样，只是波长要短得多。
Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, cannot break chemical bonds nor cause ionization in the human body.
射频波就是电磁场，但是与X射线或伽玛射线辐射等电离辐射不同的是，射频波不会打破化学键，也不会给人体造成电离辐射伤害。
