Prof. Hoecker Puts Minds at Ease
Blast Bigger Worry Than Fallout
A person has an excellent chance of surviving a nuclear attack if he has invested in a little insurance—a bomb shelter.
This was the opinion of Frank Hoecker, professor of radiation biophysics, yesterday before the Faculty Forum in the Kansas Union.
He said survival depends on where a person is at the time of the blast—the distance from ground zero and protection at the time of blast.
"A 20 MEGATON bomb released above Forbes Air Force Base would set fire to almost all wooden structures in Lawrence," Prof. Hoecker said. "Therefore, a basement shelter in a frame house would be ineffective."
A megaton is equal to one million tons of TNT.
He said the lethal dose of radioactive material is between 600 to 700 roentgens. He added a shelter should have a protective factor of 7/100 roentgens per hour.
curacy and is the equivalent of 1/600 of a lethal dosage of radioactive material.
A roentgen is a measure of ac-
"The walls of a shelter should be either eight inches of concrete, 12 to 15 inches of earth or 20 inches of sand."
HE SAID fallout from nuclear attack is one thing while test fallout is another. He added he was not frightened by fallout from the Soviet nuclear tests.
"The level of strontium 90 from the bomb tests is insignificant," he said. "It would take tons of nuclear bombs to raise the strontium 90 level to a point where adverse effect is detectable."
Advocating resumption of nuclear test by the United States, Prof. Hoecker said the American people have succumbed to a campaign of nuclear blackmail, partly self-imposed and partly encouraged by outside forces.
the Russians will "go at it again and set off some big ones.
"We have become psychologically conditioned to react to nuclear blackmail. The Russians have us in a position where we cannot carry on tests," he said.
HE ADDED the Russians have kept their capability by setting off nuclear bombs like a series of firecrackers. He said if we resume tests,
At the end of his talk, he was questioned about the effect of fall-out on food and water. He said radioactive material would contaminate food left in the open, but food in an undamaged grocery store would be safe to eat.
WATERWOULD be contaminated for only a short time, he said, because radiation decreases rapidly in water.
Speaking of milk, he said, "If the cow eats contaminated feed, the milk would be contaminated." But if in several weeks the cow would eat uncontaminated feed, the milk would be no longer contaminated.
"All strontium in the cow's blood would be filtered out by the bones. The strontium would be firmly fixed in the bone, leaving the flesh safe to eat."

Mock crime scenes will be part of the first annual Burglary and Larceny Seminar for Kansas Peace Officers here.
About 60 Kansas peace officers will be staging burglary and larceny scenes on the KU campus this week.
Mock Crimes to Be Staged Here
After the "crimes" are acted out, the officers will gather evidence, make "arrests" and present their evidence in mock trials. Conviction or acquittal of the accused will depend on the efficiency with which the evidence is gathered and presented.
PIZZA HUT
The seminar will also include classroom instruction on procedures of crime investigation involving burglary andlarceny.
The purpose of the seminar is to offer highly technical training to experienced peace officers to supplement the annual Peace Officers Training School in the summer.
The training session was planned by the Kansas Peace Officers Association, Kansas Bureau of Investigation, Kansas State Highway Patrol, KU Governmental Research Center and University Extension.
KU representatives who will work in the seminar are Ethan P. Allen, William H. Cape and B. L. Seruggs of the Governmental Research Center; Duane R. Nedrum and Paul Wilson, associate professor of law, and Karl Kappelman, University Extension.
