The average radiation dose from an abdominal X-ray is 0.7 millisieverts (0.0007 Sv), that from an abdominal CT scan is 8 mSv, that from a pelvic CT scan is 6 mGy, and that from a selective CT scan of the abdomen and the pelvis is 14 mGy. [7]
Additionally, in 2010, researchers from Virginia Tech's College of Natural Resources and Environment received a $3.4 million grant from the United States Department of the Interior to study the effects of the Deepwater Horizon oil spill in the Gulf of Mexico on piping plovers, shorebirds that have been listed as threatened since 1986.

The Virginia Tech Carilion School of Medicine is a public medical school of Virginia Tech and located in Roanoke, Virginia. The medical school is associated with the Fralin Biomedical Research Institute. Formed as a public–private partnership with the Carilion Clinic, the medical school grants the Doctor of Medicine (M.D.) degree to its ...
The roentgen or röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
During fiscal year 2012, 17 U.S. patents and six foreign patents were issued to VTIP, and 32 license and option agreements were signed. In addition, VTIP reported $2,269,991 in license revenue. [96] The Virginia Tech Applied Research Corporation (VT-ARC) is a private nonprofit corporation affiliated with Virginia Tech that was established in ...
The rep has variously been defined as 83 or 93 ergs per gram of tissue (8.3/9.3 mGy) [13] or per cc of tissue. [14] In 1953 the ICRU recommended the rad, equal to 100 erg/g as a new unit of absorbed radiation, [15] but then promoted a switch to the gray in the 1970s.
The Virginia Tech Corps of Cadets (VTCC) is the military component of the student body at Virginia Polytechnic Institute and State University.Cadets live together in residence halls, attend morning formation, wear a distinctive uniform, and receive an intensive military and leadership educational experience similar to those at the United States service academies.
Absorbed dose is a dose quantity which is the measure of the energy deposited in matter by ionizing radiation per unit mass.Absorbed dose is used in the calculation of dose uptake in living tissue in both radiation protection (reduction of harmful effects), and radiology (potential beneficial effects, for example in cancer treatment).
