Symbol for the negative decadic logarithm of the H + ion concentration (measured in moles per liter); a solution with pH 7.00 (1 Ã 10 -7 g molecular weight of H +K per liter) is neutral at 22Â°C (that is, [H + ] = [OH - ]), one with a pH value of more than 7.00 is alkaline, one with a pH lower than 7.00 is acid.
For example, the cost of a CT scanner can be as low as $65,000 for a refurbished one that produces only small images quickly. A larger and brand new CT scanner can run as high as $2.5 million. Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.Ultrasound machines are much cheaper at $10,000-$200,000, depending on brand and type. For hospitals and imaging centers, the base price for machines is just the beginning. larger and brand new CT scanner can run as high as $2.5 million.
