Both American and French designers settled on plutonium-238 as the best radioactive source. The artificially produced element emits "soft" alpha particles, which have so little energy that they will not penetrate a sheet of heavy notepaper; thus they will not harm a patient. The French put 150 mg. (about one two-hundredth of an ounce) of Pu-238 into a capsule of platinum and tantalum. The Americans put 500 mg. (one-sixtieth of an ounce) in their capsule. In both devices, the patient is sufficiently shielded from the heat of the radioactive source by its plastic container. That heat...
...walked down Divinity Avenue, a green MG drove by and one of the professors waved and honked. "What do you say we forget about politics and participate in the cultural revolution this afternoon?" Flip said. It seemed the only thing...
When a patient has any one of a number of infections, his physician may write on a prescription blank: "Tetracycline, 250 mg. #16. Sig. 1 caps, q.i.d." That dosage of 250 milligrams is standard for any adolescent or adult, whether a 100-lb. girl or a 300-lb. man. Equally standard is the one capsule four times a day for about four days...
...rare exceptions, the medicine bottle should be labeled with the name of the drug. "The obsolete apothecary system of grains, ounces and drachms is dangerous and unnecessary. The ancient symbols for ounce and drachm are nearly alike, and fatal over doses have resulted. The abbreviation gr. (meaning grain, 60 mg.) is easily mistaken for gram (1,000 mg.), also with catastrophic consequences." Instead of a dubious decimal point, the doctor should use a vertical line...
...military, of course, has tremendous bases all over the South. There's a big Air Force one right across the street from the MG dealer's in Montgomery. Hitchhiking back from picking up a new water pump, we got a ride from a big smiling native Brazilian para-medic in his air conditioned Volkswagen bus with two little children. During the week he flies over to Vietnam and parachutes into the combat areas to save the wounded soldiers. He does stuff for them right there while the shooting is still going on, and then flies all the way back...
