Other uses of radiography include the study of the organs in the abdomen, such as the liver and bladder; chest radiography for diseases of the lung, such as pneumonia or lung cancer and mammography to screen for breast cancer.X-ray fluoroscopy is used to detect a number of diseases associated with the stomach and intestine, genitals and urinary tract.
Is a 6,000 year age for the earth based on different facts than a billion year age for the earth? It's interesting that these same tests, when used on new rocks (from volcanos such as Mt. Helens) give ages for these new rocks that say they are millions of years old. #2 - It took millions of years to build up all those rock layers the fossils are buried in. #3 - There are scientific methods used to date rocks that tell us they are millions of years old. The problem is that using these methods you'll probably get 100 different ages for the rock. We must look at what we have in the present, and follow that evidence to wherever it leads us. Didn't it take millions and millions of years for dinosaurs to turn into oil? There is a refinery in Texas that takes in turkey carcasses and turns them into oil in three hours. Given the right conditions of temperature, pressure, etc., it only takes a few hours. A lot of water (say from Noah's global flood), over a short time can easily create millions of rock layers. Lots of dead things killed by Noah's flood--which is exactly what we see. There are about 100 methods of dating rocks based on measuring radioactive decay.Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment.Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.Radioactive materials are used to inspect metal parts and the integrity of welds across a range of industries.
Industrial gamma radiography exploits the ability of various types of radiation to penetrate materials to different extents.They are particularly useful where process optimization can bring material benefits, such as in the transport of sediments.Radiotracers are also used in the oil and gas industry to help determine the extent of oil fields.Traditionally, medical X-ray images were exposed onto photographic film, which require processing before they can be viewed and take up a lot of space in hospitals and doctors’ offices.Digital X-rays, which overcome these problems, have therefore become increasingly popular in radiography.By adding small amounts of radioactive substances to materials used in various processes it is possible to study the mixing and flow rates of a wide range of materials, including liquids, powders, and gases and to locate leaks.
