Immunity and electromagnetic fields
Environmental Research, 2021Despite many studies, the question about the positive or negative influence of electromagnetic fields (EMF) on living organisms still remains an unresolved issue. To date, the results are inconsistent and hardly comparable between different laboratories.

Electromagnetic fields and cells
Journal of Cellular Biochemistry, 1993AbstractThere is strong public interest in the possibility of health effects associated with exposure to extremely low frequency (elf) electromagnetic (EM) fields. Epidemiological studies suggest a probable, but controversial, link between exposure to elf EM fields and increased incidence of some cancers in both children and adults.

A quantization of the electromagnetic field
Canadian Journal of Physics, 1983Quantization of the electromagnetic field in a class of covariant gauges is performed on a positive metric Hilbert space. Although losing manifest covariance, we find at the free field level the existence of two physical spaces where Poincaré transformations are implemented unitarily.

Electromagnetic Fields and Bones
JAMA: The Journal of the American Medical Association, 1982The use of pulsing electromagnetic fields (PEMFs) and direct-current stimulation for the treatment of delayed and nonunion of fractures is proving to be a major advance in traumatic orthopedic surgery. In this issue ofThe Journal(p 623), Bassett and his co-workers summarize their experience in the use of PEMFs for nonunited fractures and failed ...
