A 1971 French study of O.R.T.F. broadcasting technicians reported reversible functional troubles after work in high-frequency fields and no progressive disease attributable to that work.

Plain English Summary

Summary written for general audiences

A French work-safety study presented in 1971 by M. Deroche drew on 10 years of observations at O.R.T.F. (French broadcasting) transmitters. Long waves (15 KHz to 3 MHz) were progressively dropped from the investigation because surveys between 1960 and 1963 showed very few troubles, not exceeding the average percentage in comparable groups. For 3 to 300 MHz, a questionnaire sent to 150 technicians drew 134 responses and identified reversible functional troubles that ceased outside work, with no progressive disease attributable to work in high-frequency fields.

Why This Matters

This 1971 study by M. Deroche reports 10 years of work-safety observations at O.R.T.F. transmitters, where troubles appeared at the least favored transmitters as power increased in the 3 to 300 MHz range. The functional troubles identified included fatigue, migraines, insomnia, circulatory stasis, hypotension and drowsiness at work. They were reversible and ceased outside work, and no technician reported a specific condition confirmed by a treating physician or hospital service.

Quick Questions About This Study

Technicians reported reversible functional troubles that cease outside work, including excessive fatigue, migraines, insomnia, circulatory stasis, hypotension and drowsiness at work. No progressive disease attributable to work in high-frequency fields was reported.
Surveys between 1960 and 1963 showed a very low proportion of troubles with long waves (15 KHz to 3 MHz), not exceeding the average percentage in comparable groups, so the investigations progressively concentrated on higher frequencies.
The observations covered 10 years within the work-safety program at O.R.T.F. across the transmitters. A questionnaire survey of 150 technicians, completed at the end of 1969, drew 134 responses.
The results led to the conclusion that there was no progressive disease attributable to work in high-frequency fields, since no technician reported a specific condition confirmed by a treating physician or hospital service. Reversible functional troubles that ceased outside work were clearly identified.
Long waves from 15 KHz to 3 MHz were progressively dropped from the investigations. Attention went to decametric and metric waves from 3 MHz to 300 MHz (about 100 m to 1 m), where troubles appeared at the least favored transmitters as transmitter power increased.
