ID Number		419
Study Type		In Vitro
Model		2.9 GHz (CW) exposure to human lymphocytes and analysis of growth
Details		Human lymphoblastoid cells were exposed to 10 cm (PW) microwaves for 3 or 5 days at either 7 mW/cm2 for 4 hr/day or 20 mW/cm2 for 15 min/day using a box horn antenna in an anechoic chamber. After the 3 day exposure, the number of lymphoblastoid transformants increased 30%, and after 5 days the number of lymphoblastoid transformants increased 60%. In addition, after 3 days the number of lymphoid macrophages increased from 0 to 1.2% at 7 mW/cm2 and after 5 days the number of lymphoid macrophages increased to 12%. Sporadic mitoses (1-3%) were also observed in most exposed cultures but not in control cultures. Fragmented nuclei, bridges joining separated parts of nuclear material, and vacuolization of nuclei were also observed among transformed cells.
