Kearny Fallout Meter
From Wikipedia, the free encyclopedia
The Kearny Fallout Meter or KFM is an expedient radiation meter designed to be able to be constructed immediately before or during a nuclear attack by someone with a normal mechanical ability and from common household items. It also is a science project demonstrating the effect of ionizing radiation.
An electrostatic charge is placed upon two aluminium foil leaves. As radiation strikes the meter the foil leaves lose their charge and start to droop. This droop can be measured and a rate be established.
It was developed by Cresson Kearny from research performed at Oak Ridge National Laboratory and published in the civil defense manual Nuclear War Survival Skills (ISBN 0-942487-01-X). The plans are formatted so that they could be quickly printed in local newspapers.
