My young daughter was wearing a beat up old watch a friend had given her.
I asked her, "Does it tell the time?"
My daughter looked at me and said, "No, you have to look at it."
Medical research reactorIn 1959, at Brookhaven National Laboratory in Upton, N.Y., the first U.S. atomic reactor built specifically for medical research, Brookhaven Medical Research Reactor, reached criticality. The BMRR was a 5 megawatt, modified tank-type reactor, which superceded the Brookfield Graphite Research Reactor. It produced a neutron flux of as many as 20 trillion neutrons per square centimeter per second. The reactor was mainly used for developing and testing boron neutron capture therapy (BNCT), a promising treatment for patients with a deadly form of brain cancer called glioblastoma multiforme. BNCT uses radiation and a boron compound to destroy cancer cells while leaving healthy cells intact. Use of the reactor ceased in Dec 2000.« |
