  • Therefore, if radiation therapy inhibits neurogenesis in the hippocampus it would lead to the cognitive decline observed in patients who have received this radiation therapy. (wikipedia.org)
  • General surgical aspects as the guiding principle of action Exclusion of certain conditions as inflammation in large body cavities, stiff thick-walled cavities and empyema Bacteriological and experimental analysis of the reaction of small radiation dosage Concerning the last point, Carl Fried did further research and investigated the serum of irradiated patients which had the tendency to inhibit or kill specific germs within a certain period of time. (wikipedia.org)
  • Like angiography, CTA exposes patients to high dosages of radiation. (wikipedia.org)
  • Even small changes may be measured, making MRA a useful tool for monitoring disease progression without exposing patients to the radiation of direct angiography or CTA. (wikipedia.org)
  • Ultrasonography is a popular first-line investigation for diagnosis because it is relatively quick, cheap, noninvasive, and does not expose patients to radiation. (wikipedia.org)
  • Technical aspects include positioning patients for X-rays, determining appropriate angle and height of X-ray equipment, and calculating radiation dosages needed to create X-rays of the appropriate density, detail, and contrast, enabling the physician to make an accurate diagnosis.

  • Even with collective evidence, it was not until the 1950s, thanks in part to W.F. Bale, that it was accepted by researchers that radon was the major cause of radiation damage to lung tissue in mine workers. (wikipedia.org)
  • Its absorption, transportation, and utilization A Combined Voltage Regulating and Quenching Circuit for the Geiger‐Müller Counter Radiation dosage to lungs from radon and its daughter products, Bale and Shapiro. (wikipedia.org)
  • The health hazards of low doses of ionizing radiation are unknown and controversial, because the effects, mainly cancer and genetic damage, take many years to appear, and the incidence due to radiation exposure can't be statistically separated from the many other causes of these diseases. (wikipedia.org)
  • RESULT: A comparison of the recommended borders to the actual boundaries of the radiographs taken show an additional exposure to radiation in all three procedures: 85% of chest radiographs also included the whole abdomen, 64% of abdomen radiographs included both thigh and upper chest and 62% of chest and abdomen radiograph included the thigh.

  • The Solar Cell Radiation Handbook says: "Flares capable of producing large proton events tend to occur when the rate of change in sunspot number becomes greater" -- in other words, the peak flare period is before solar max and: "The size of each event is almost randomly distributed over an 11 year cycle.
