Radiation and brain calcium: a review and critique.

Serious controversy pervades the scientific study of radio-frequency (RF) radiation and its biological effects. The issues range broadly from international differences in safe exposure standards to questions pertaining to the neurological symptoms purportedly induced by electromagnetic radiation. In a more specialized vein, there is great concern in the discipline about the influence of different sources of radiation on the activity of calcium in the brain. A principal and very realistic reason for this concern stems from the pivotal importance of calcium ions in the normal functioning of the brain in all of its myriad complexity. The purpose of the review is to critically evaluate from an unbiased and "non-involved" viewpoint the major findings on the possible interaction between calcium ions and various radiation sources. Background information is also considered as it relates even indirectly to hypothetical mechanisms that might be used to explain any possible shift in Ca++ ion kinetics. Finally, an inclusive critique is presented which deals with the bench-top methods and strategy used in the conduct of calcium-radiation experiments.
