And that depends on being able to see the lower-energy radiation, in order to pinpoint what it was that exploded (gamma rays are impossible to focus, so the location of a burst is known only approximately).

Conventional CT scans are used to work out the shape of the place where a dose of radiation needs to be concentrated in order to attack a tumour without damaging nearby healthy tissue.

Once the cancerous area is precisely targeted, only the intensity of the laser radiation needs to be turned up in order to irradiate, or burn off, the tumor.

When we talk about telescopes, we're usually referring to devices that "see" the visual spectrum of light, but astronomers also build telescopes that gather radiation like radio waves and X rays in order to peer deep into outer space.

Before I order a CT Scan that adds to the cumulative ionizing radiation the patient has accumulated and spend a large sum of money, I want to eliminate the possibility that it could be addressed with a simpler, less invasive approach.

During radiation therapy, you're positioned on a table and a large machine moves around you, directing radiation beams to specific areas of your body in order to target your cancer.

She has a doctor's order for the screening but has put it off, noting conflicting reports and concerns about radiation exposure.

They carried out detailed statistical analysis, in order to assess whether there was a link between cases of cancer and above average levels of radiation.
