Californium coal monitorIn 1969, the use of californium-252 radioactive material in monitoring the sulphur content of coal was announced by the Atomic Energy Commission. Using this intense neutron source to measure the sulphur content of coal, as it moved on a conveyor belt through a coal processing plant, would enable better control of the air pollution caused by burning coal. When coal is burned, for example at electrical power plants, its sulphur is released as sulphur dioxide, a pollutant which needs to be reduced, because it contributes to acid rain. In turn, this results in acidified soils, forest damage and building corrosion. A shipment of 18 micrograms of the isotope had been sent from its Savannah River plant to South Carolina to the Bureau of Mines research centre at Morgantown, West Virginia. (A microgram is one millionth of a gram.)«
A judge was interviewing a woman regarding her pending divorce, and asked, "What are the grounds for your divorce?"
She replied, "About four acres and a nice little home in the middle of the property with a stream running by."
"No," he said, "I mean what is the foundation of this case?"
"It is made of concrete, brick and mortar," she responded.
"I mean," he continued, "What are your relations like?"
"I have an aunt and uncle living here in town, and so do my husband's parents."
He said, "Do you have a real grudge?"
"No," she replied, "We have a two-car carport and have never really needed one."
"Please," he tried again, "is there any infidelity in your marriage?"
"Yes, both my son and daughter have stereo sets. We don't necessarily like the music, but the answer to your questions is yes."
"Ma'am, does your husband ever beat you up?"
"Yes," she responded, "about twice a week he gets up earlier than I do."
Finally, in frustration, the judge asked, "Lady, why do you want a divorce?"
"Oh, I don't want a divorce," she replied. "I've never wanted a divorce. My husband does. He said he can't communicate with me!"
