In the study of X-rays and gamma-rays up to the TeV regime, their absorption by the atmosphere (by 50% at 30 km altitude for 1 MeV photon) requires the development of space applications. The science goals of the mission define which technological benchmark should be maximised (e.g. ...
Gamma rays: Gamma rays have the most energy and shortest wavelength of the entire spectrum. Nuclear explosions and radioactive atoms generate these rays. Gamma rays can kill living cells, and medical professionals sometimes use them to destroy cancerous cells. In deep space, gamma ray bursts occu...
So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible light, violet has the most energy and red the least. The whole range of frequencies and energies, shown in the accompanying figure, is known as the ...
The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source (in short: radio quasar) 3C 279, at a distance of more than 5 billion light-years (a redshift of...
For example, your immune system can detect cancer in early stages and eliminate it in many cases. Bacteria and Viruses Your body is a multi-cellular organism made up of perhaps 100 trillion cells. The cells in your body are fairly complicated machines. Each one has a nucleus, energy ...
or CCD. Some space telescopes use a complementary metal-oxide-semiconductor (CMOS) active-pixel sensor, such as theWISPR imageron the Parker Solar Probe. These sensitive instruments can detect photons from the infrared to gamma rays because of how photons interact with the electrons in the sensors...
The PET scanner machine detects these gamma rays, and with the help of advanced computing technology, the machine can create a 3D image of the brain’s activity. At times, PET scans are used in conjunction with other brain imaging techniques like a CT scan or fMRI to get enhanced informatio...
What about chest X-rays? Chest radiography is useful but cannot provide a conclusive diagnosis on its own, and needs to be followed by sputum testing. Abnormal X-rays do suggest TB, but other lung conditions can also produce abnormalities on radiography. So, only relying on chest x-ray can...
What were X-rays used for? X-rays are commonly used in medicine for imaging internal structures to diagnose conditions such as fractures, tumors and dental issues. Additionally, X-rays find applications in industrial inspections, security screening, scientific research and cancer treatment through radi...
Gamma rays are the only type of nuclear radiation that comes from energy instead of fast-moving particles. Remember that fission part especially. It's going to keep coming up as we discuss the inner workings of nuclear bombs. Nuclear Fission Nuclear fission is a reaction in which the ...
