The narrow-range probe achieved a maximum sensitivity of 0.5 SmW/cm² in X band and a response time under 10 ms. The wide-range probe showed a maximum sensitivity of 5 SmW/cm² and a response time of about 100 ms. Calibration curves were obtained at 0.4 GHz, 1.4 GHz, and 2.4 GHz, and sensitivity decreased toward lower microwave frequencies.

Experiments using a parallel plate waveguide measured RF absorption in rats and biological-phantom prolate spheroids across frequencies and polarizations. The results correlated well with free-space irradiation findings. Peak absorption occurred when the electric field was parallel to the long body axis at frequencies where the body length was about one-quarter wavelength, with absorption 2.5 to 3.5 times the shadow cross-section.

Muscle penetration depth followed the expected frequency inverse behavior and matched predictions from lower-frequency data by Schwan and Li. Fat penetration depth agreed within 50% of extrapolated data and showed relatively large values of several millimeters around 50 GHz. Muscle tissue measurements indicated substantial multimoding, so the reported dielectric constant and conductivity values represent only upper limits.

The apparatus is a 6 m long, temperature-controlled water alley with automatically raised and lowered end platforms that record swim speed on each traverse. Water temperature was held at 24°C with a gradient not exceeding .3°C across the alley. An avoidance-conditioning and dunking procedure trained more than 90% of rats to swim reliably at 23°C. The platform rest period used in most experiments was 30 seconds. The automated system operated reliably for extended sessions with trained rats.

Only 10 documented cases of EMI affecting pacemakers were found, and none were serious or fatal. The authors concluded that environmental EMI does not constitute an important clinical problem for pacemaker patients at this time.

Researchers modeled the human skull as six concentric layers (skin, fat, bone, dura, cerebrospinal fluid, and brain) and calculated microwave absorption across the 0.1-3 GHz band for skull radii of 7 cm and 10 cm. The inhomogeneous model showed a broad absorption peak near 2.1 GHz with peak values of 1.52 for the 7 cm radius and 3.38 for the 10 cm radius, a peak not present in the homogeneous model.

Researchers exposed albino mice to acute microwave radiation at 62±5 milliwatt/cm² for 11 minutes and to chronic radiation at the same intensity for 20 days at 6 minutes daily. Survival increased one and a half fold with cordiamine treatment. No positive effect of ephedrine was revealed.
