この研究は、10人の被験者を対象にしたパイロット研究において、典型的な都市レベルをかなりの程度下回る10（-12）W / cm 2未満の電力密度へのばく露により、脳電図および行動の一時的変化が見られた、と報告している。 ばく露したのは。1〜960MHzの連続波および8.5〜9.6GHzのパルス変調波である。 タンパク質結合水の緩和周波数は100〜1,000MHzの間であると考えられているので、10（-15）W / cm2 の130〜960MHz連続波の無線周波エネルギーがもたらした、被験者の大部分で観察されたの脳電図変化のメカニズムの根底は、吸収と量子効果であるかも知れない、などと考察している。

To identify effects on the human nervous system of low power radiofrequency energy.
Each signal source was slowly tuned through its range.
| 周波数 | 0.1–960 MHz |

| ばく露時間 | continuous for 50 min |
| Additional information | Woman were tested within the 250 to 960 MHz range only. |
| Modulation type | CW |

|---|---|
| Distance between exposed object and exposure source | 1 m |
| チャンバの詳細 | Tests were made at various locations inside and outside of a Faraday shielded room that was 6 m square and 2.5 m high. Shielding consisted of two welded-seam sheet iron walls 10.2 cm apart. |
| ばく露装置の詳細 | Subjects were seated (usually with their eyes closed) such that they could not see equipment or operator and did not know the exposure conditions. The antenna was a 1 m wire rod monopole supported by a wooden yardstick. It was placed parallel to and 1 m from the upper torso and head on the left side. (Right side, left rear, and right rear were tried but effects were negligible.) |
| Additional information | The dial accuracy of the generators was within 5%. |

| ばく露装置の詳細 | Subjects were either standing or sitting with their eyes closed 1 m from the open waveguide output oriented perpendicular to the sternum at the level of the 5th intercostal space. |
| Additional information | Frequency-range accuracy and pulse wave shapes of the generator were inconsistent and values could only be used as close approximations. |

The results suggest that very low power density radiofrequency can interfere with the normal brain-wave patterns of humans. And if these patterns are meaningful in terms of mood and behavior, then radiofrequency affects these parameters as well. Since the relaxation frequency of protein-bound water is considered to fall between 100 and 1000 MHz, absorptions and quantum effects may be the mechanistic basis for the EEG changes revealed in most of the subjects produced by 10-15 W/cm² CW (continuous wave) radiofrequency energy of between 130 and 960 MHz.
