Acute heart attack patients received an average total dose of ionising radiation equal to 725 chest X-rays from medical tests during their hospital stay, according to research presented at the ...
On 9 April the Sun erupted and blasted a bubble of hot, ionised gas into the solar system. The eruption was observed in unprecedented detail by a fleet of spacecraft, revealing new features that are ...
... out of Mars Express’s view. The transmission blackout window is caused because of ionisation around the probe, which builds up as the lander descends through the atmosphere and only very weak signals ...
... ? Microwaves with frequencies from a few hundred gigahertz (GHz) up to slightly over 1 terahertz (THz), penetrate just a short distance into surfaces without the ionising damage caused by X-rays...
... disease. The study, the first of its kind to report the relationship between low dose ionising radiation from diagnostic procedures and the risk of prostate cancer, was funded by the Prostate Cancer ...
... . The relatively high number of redshift 7.5 galaxies claimed in this survey suggests that most of the ionising energy was produced by dim and abundant galaxies rather than large, scarce ones.
"The ...
... in fact huge clouds of glowing hydrogen gas. Ultraviolet radiation from newly born, massive stars is ionising the gas in these clouds, causing the great regions of hydrogen to glow red. These star ...
... for setting optimal parameters for radiation treatment of prostate cancer. This approach guarantees that the ionising radiation only destroys tumour cells and does not affect other organs in the ...
... , patients have to undergo an increasing number of scans and tests that may involve the use of ionising radiation to detect the source and scope of an ailment. However, this practice could also put ...
Gum 29 is a huge region of hydrogen gas that has been stripped of its electrons (ionised) by the intense radiation of the hot young stars located at its centre. Astronomers call this an HII ( ...

... and structural properties can be obtained. The thermodynamic properties – temperature, density and ionisation state, were all measured using a combination of non-invasive, high accuracy, X-ray ...
... are commonly performed in conjunction with scintigraphic and manometric techniques, despite the use of ionising radiation and catheters, for each of these additional techniques, respectively...
... to shield their spacecrafts with a portable magnetosphere - scattering the highly charged, ionised particles of the solar wind and flares away from their space craft.
Computer simulations done by ...
... , massive star in its centre is emitting huge amounts of ultraviolet radiation, which ionises the surrounding gas, stripping the electrons from hydrogen atoms and producing the characteristic red glow ...
