It's both natural and man-made. A natural source of ionizing radiation is radon, a radioactive material found underground. X-rays are a good example of man-made ionizing radiation. The three types of ionizing radiation we're going to discuss here are alpha particles, beta particles and ...
The radon sensor in all of our products is made by Airthings and uses "alpha spectrometry" to measure the level of radon. It was designed by our in-house CERN scientists and the invention is patented. CERN stands for the European Organization for Nuclear Research. The radon sens...
As with many of mankind's monumental discoveries, X-ray technology was invented completely by accident. In 1895, a German physicist named Wilhelm Roentgen made the discovery while experimenting with electron beams in a gas discharge tube. Roentgen noticed that a fluorescent screen in his lab starte...
Radiation exposure can have varying effects, depending on the dose received, and what the exposure was. Certain elements, when the exposure is internal, will deposit in various organs or bones. Radioactive Iodine tends to seek out the thyroid (making it useful in cancer treatment) whereas Stront...
Granite is made up of interlocking mineral crystals, the most common being feldspar and quartz. But an array of other minerals can be included, and these make each piece of granite unique. Feldspar will give gray, pink or red highlights; the light gray veins are quartz; and the black is ...

By YU Haoyuan Since the outbreak of the COVID-19 pandemic, the global digital economy has made rapid growth. When one of the world's largest shopping events Double 11 comes around (China's Single's Day sale that takes place annually online on November 11), it generates a flurry of...
but curiosity," Yuan said, emphasizing that curiosity is a basic human trait and the most primitive, powerful, and strongest motivation behind basic research. Some groundbreaking scientific and technological discoveries are made from scratch and often rely on basic research rather than applied research...
This article was updated in conjunction with AI technology, then fact-checked and edited by a HowStuffWorks editor. Water is the essence of life. No living thing on Earth can survive long without it. In its purest form, it's odorless, nearly colorless and tasteless. It's in your body, ...
How is gold made with alpha decay?Question:How is gold made with alpha decay?Alpha Decay:Alpha decay is a form of nuclear decay that results in alpha radiation, the emission of an alpha particle from the unstable nucleus of certain atoms. Not all unstable atoms decay through alpha decay, ...
