Appropriately for a station with roots in a newspaper, WIVB-TV has a strong news tradition. WBEN-TV was the early news leader in Buffalo until approximately 1972, when (briefly) WGR-TV and then (more long-term) WKBW-TV overtook it. Channel 4 then spent most of the next 30 years as a solid, if usually distant, runner-up to WKBW-TV, well ahead of ...
Many years ago radium-226 and radon-222 were used as gamma-ray sources for industrial radiography: for instance, a radon-222 source was used to examine the mechanisms inside an unexploded V-1 flying bomb, while some of the early Bathyspheres could be examined using radium-226 to check for cracks.
Often called the father of nuclear medicine, Lawrence treated a leukemia patient with radiophosphorus, which was the first time a radioactive isotope has been used to treat human patients. [4] Another pioneer in the field, Sam Seidlin, in partnership with Saul Hertz, treated a case of thyroid cancer with radioactive iodine (I-131) 1946. [5]
Many other isotopes have been used in specialized radiopharmacological studies. The most widely used is 67 Ga for gallium scans. 67 Ga is used because, like 99m Tc, it is a gamma-ray emitter and various ligands can be attached to the Ga 3+ ion, forming a coordination complex which may have selective affinity for particular sites in the human body.
These standards include water and shock resistance, large gamma energy range, detection of gamma and neutron sources, automatic system calibration, and temperature stabilization. [4] These instruments are equipped with a specific ANSI library that contains a list of standard isotopes. [ 5 ]
Archaeological materials, such as bone, organic residues, hair, or sea shells, can serve as substrates for isotopic analysis. Carbon, nitrogen and zinc isotope ratios are used to investigate the diets of past people; these isotopic systems can be used with others, such as strontium or oxygen, to answer questions about population movements and cultural interactions, such as trade.
Sazerac, which owns Buffalo Trace, confirmed that the national TV commercial was the first of an on-going advertising campaign that will air throughout the fifth season on the Paramount Network.
The radium isotope (226 Ra) used has a half-life of about 1,600 years, [7] so radium dials remain essentially just as radioactive as when originally painted 50 or 100 years ago, whether or not they remain luminous. Radium dials held near the face have been shown to produce radiation doses in excess of 10 μSv / hour.
