Researchers exposed crayfish and prawn nerve clusters to 11 gigahertz microwave radiation at 300mW/mm² power density.

In 1967, researchers discovered that microwave radiation could transform human lymphocytes (white blood cells) into blast-like cells in laboratory cultures. This transformation normally requires chemical stimulants, but microwaves alone triggered the same cellular changes. The finding suggests microwave radiation can fundamentally alter immune cell behavior.
