“According to scientific papers that have been sent to this country, scientists in the Soviet Union several years ago studied 45 persons who had worked in 400,000‐volt and 500,000‐volt switch yards two to five hours a day for several years.

Forty‐one of the 45 showed, immediately after exposure, certain physical symptoms included “instability” of pulse and blood pressure, tremors of arms and legs, and sweating. About 30 per cent of the male subjects reported diminished sexual vigor. Ten or more subjects showed slowed heartbeat, slowed electrical conduction in the heart and anemia.”
