A joint meeting (Munich, Germany; Nov 8–10, 2017) between ICRP and ICNIRP exchanged views on the scientific/ethical basis and principles of protection, aiming to increase mutual understanding, reach a common understanding of the state of protection systems, and explore continued collaboration. The organizations agreed in principle to strengthen communication and collaboration, and noted commonalities and differences between ionizing and non-ionizing radiation protection systems (e.g., emphasis on optimization vs keeping exposures below thresholds).

External electromagnetic radiation modeled as a cosine function induces mode transitions in membrane potential of a single neuron model, including periodic, quasi-periodic, and chaotic behaviors depending on the frequency and amplitude of the radiation. Frequency plays a key role in determining the behavior, with chaotic motion occurring in a specific frequency interval.

In male white rats, low-intensity ultrahigh-frequency electromagnetic radiation (EMR UHF) and a low-intensity low-frequency magnetic field applied during the post-irradiation period (within 21 days after radiation exposure) were reported to enhance metabolic and regenerative processes in the testes and liver. The magnetic field was reported to largely intensify antioxidant activity, while EMR UHF preferentially stimulated biosynthetic processes and cellular/intracellular regeneration.

Rats exposed to a 50 Hz magnetic field showed significantly higher morphine analgesic effect compared with morphine-only rats (p < 0.05). In morphine-tolerant rats, magnetic-field exposure was associated with significantly higher analgesic effect than in morphine-tolerant controls (p < 0.05), interpreted as reduced morphine tolerance.

In rat BMSC, simultaneous exposure to 50 Hz low-frequency EMF with high-concentration NO donor (Deta-NO, 1 mM) was associated with down-regulation of stemness markers and up-regulation of neuronal differentiation markers, along with decreased proliferation and morphology changes. Low-concentration NO donor (50 µM) was associated with decreased Nestin and DCX without change in Oct4, interpreted by the authors as protection of the stemness state.
