The vitamin niacin (nicotinic acid,C6H5NO2 ) can he isolated from a variety of natural sources, such as liver, yeast, milk, and whole grain. It also can be synthesized from commercially available materials. Which Source of nicotinic acid, from a nutritional view, is best for use in a multivitamin tablet? Why?
Radiation exposure to human beings is usually given in rems (radiation equivalent for man). In SI units, the exposure is measured in sieverts (Sv). One rem equals 0.0100 Sv. At one time, the exposure due to the nuclear reactors in Japan wras measured to be 8217 mSv/h. How many rems would a person exposed to the radiation for 35 min have absorbed? If one mammogram gives off 0.30 rems, how many mammograms would that exposure be equivalent to?
