GIANT MAST CELLS—A SPECIAL DEGENERATIVE FORM PRODUCED BY MICROWAVE RADIATION
E. J. Valtonen · 1966
1966 research found microwave radiation caused abnormal degenerative changes in immune system mast cells in rodents.
Plain English Summary
This 1966 study examined how microwave radiation affects mast cells in rodents, specifically investigating the formation of abnormally large, degenerative mast cells. The research focused on changes in peritoneal fluid and explored both thermal and non-thermal effects of microwave exposure on these important immune system cells.
Why This Matters
This early research represents one of the first scientific investigations into how microwave radiation affects mast cells, which are crucial components of our immune system responsible for allergic reactions and inflammation. The fact that researchers in 1966 were already documenting 'giant' degenerative forms of these cells after microwave exposure suggests biological effects that go beyond simple heating. Mast cells are particularly significant because they're found throughout the body and play key roles in immune responses, wound healing, and maintaining tissue integrity. What makes this study especially relevant today is that microwave frequencies are now ubiquitous in our environment through WiFi routers, cell phones, and smart devices. While the specific exposure levels in this 1966 study may differ from modern devices, the fundamental question remains: are we seeing similar cellular changes in humans exposed to the constant low-level microwave radiation that now surrounds us daily?

The response of the mast cells of the peritoneal fluid to the microwave radiation was somewhat surprising. The expected reaction was degranulation and disruption, which usually are the immediate occurrences when mast cells are subject to irritation of any kind. It seems obvious that the giant mast cells are not formed by fusion of two or more cells, they are not so-called quasi mast cells (macrophages containing mast cell granules), nor are they the product of some disorder in the mitosis. It seems rather that they are a result of some disorder in the internal metabolism of the cells themselves. This process is probably degenerative by nature. The process is, however, not very grave, since the staining properties of the mast cell did not change but only became somewhat weaker. The fact that the other cell types in the peritoneal fluid showed no changes points to the probability that the mast cells are more sensitive than other cells or that they have a special reaction which the other cell types do not have. Since the mere heating of the tissues does not produce giant mast cells, their formation must be regarded as a non-thermal effect of the microwave radiation.
