Earl Cook · 1975

This 1975 analysis examined how high-energy industrial society affects public health, finding that while energy-intensive development improved medicine and nutrition, it also created new health challenges. The study highlighted that indirect health consequences from energy dependence may be harder to address than direct pollution effects.

Burns caused by simultaneous use of diathermy and ECG

Larsen JP, Eriksen T · 1975
