He said of the two types of radiation burns, those produced from the flash and those from the flames of ignited material, injuries produced by flames were more severe.
Based on an analysis of persons injured by the two bombs dropped on Japan, he said it was found that clothing and other covering can protect to some degree against the flash.
The safest level of radiation exposure for humans is "0," a KU radiation biophysics professor said last night, but practical steps can be taken to protect against harmful effects of radiation and radioactive fallout.
Prof. Shaw pointed out that food subject to radiation does not become radioactive. However, radioactive material deposited on the food can be taken into the body.
OTHER DAMAGE TO human life results from "prompt" radiation, or the direct absorption of rays from the explosion, and "residual" radiation, that produced from radioactive particles, he said.
Nuclear Weapons Effect Explained
PROF. SHAW explained some of the technical aspects of radiation and its measurement and also touched on other effects of nuclear weapons.
ALPHA AND BETA RAYS,which can cause external radiation poison unless the body is shielded by clothing or other means, will cause internal poison only when absorbed into the body with food, water or air. Prof. Shaw explained.
Edward I. Shaw, associate professor of radiation biophysics, spoke to about 75 persons at the Lawrence High School on the biological effects of nuclear weapons.
Thus eating and drinking food with radioactive particles becomes the greatest long range problem following a nuclear explosion, ne said.
He said the safest procedure is to eat food that has been in a tight container after making sure the container has been washed. Food with a hard natural covering is also safe if the covering is washed or pared off, he said.
Since different radiation rays have different intensities, generally only the Gamma and neutron rays cause internal body damage from exposure.
the body, and particularly the hair and folds in the skin, should be washed to protect against radiation poison, he added.
In a brief question period, Prof. Shaw was asked about the genetic effects of radiation.
PROF. SHAW said even contaminated water could be used in the cleaning process since the poison material would be highly diluted and less concentrated than on the material that is being washed.
YAF May Schedule Anti-Communist Film
He said the area was one in which there is great disagreement.
Tentative plans to sponsor an anti-Communist film and a conservative speaker were made by the KU chapter of the Young Americans for Freedom Wednesday night.
The film, "Red China — Outlaw" sponsored by the Committee-of-One-Million, an organization working for the continued withholding of United Nations membership to Red China, may be shown here Nov. 14.
"NEARLY ALL AGREE that
Much of the discussion was "off the record."
Leonard E. Read, president of the Foundation for Economic Education, may visit KU on Nov. 9 or Nov. 13 to speak to the group.
Tough Turf Recipe Sought
UNIVERSITY PARK, Pa — (UPI)
—Pennsylvania State University agronomists are seeking a "recipe" for artificially combined soils best suited to grow athletic field turfs and withstand the battering of football, tennis and golf enthusiasts.
Fifteen students joined YAF at its organizational meeting held three weeks ago. About 25 students attended the meeting last night.
there would be some genetic effects," he said. But he added questions of how much effect would result from what amount of radiation or what effect the dose rates might have was an area of controversy.
To another question of what can be done for a person exposed to radiation, Prof. Shaw said there is almost nothing that could be done short of professional medical care.
Short of that, he recommended protection against further exposure and the providing of maximum comfort to the victim.
The lecture was the third of five being sponsored by the University Extension Division and the Lawrence Adult Education Department on fallout and survival.
