この研究は、ウサギに650 MHz電磁界（EMF）の全身ばく露を長期間（2年間）連続的に行い、ばく露から12ヶ月後または18ヶ月後に全身的な影響を調べた。影響評価項目は、体重、体質重、肝臓、脾臓、脳の形態、肝臓のアポトーシス率とグリコーゲンの分布である。その結果、2年間の連続ばく露によって引き起こされた変化のタイプと程度は、ばく露後の時間経過（12ヶ月または18ヶ月）によって異なっていた；変化のタイプと程度は臓器によっても異なっており、同じ臓器でも個体によって異なっていた； いくつかの影響は、１２ヶ月後の観察群でのみ見られ、18ヶ月後の観察群では見られなかった；このことは、ある種の適応反応、または長期的な回復を示唆する、と報告している。

To clarify the potential severe damage due to electromagnetic fields generated by radio and television transmitters, by investigating the morphological changes of liver, brain, and spleen in rabbits.
Two groups of rabbits were continuously exposed for 2 years followed by 12 months (group 1, sacrificed after 12 months after the end of treatment) or 18 months (group 2, sacrificed 18 months after the end of treatment) of post-exposure.
Modulation type: FM
ばく露時間: continuous for 2 years

|ばく露装置の詳細||the exposure room was shielded with a double tubed cell of aluminum(180 cm high x 300 cm long x 150 cm deep) which gave the room a characteristic of a resonant multimode cavity. 24 cages (38 cm high x 60 cm long x 50 cm deep) each containing a single rabbit were located in the middle of the aluminum cell. EMF was transmitted with the help of panels which were located in the room.|

The continuous exposure resulted in modifications whose types and intensities were related to the time of post-exposure (12 or 18 months, respectively), The type and the extent of changes were different in different organs and -with regard to the same organs - they varied from animal to animal. A number of effects were revealed only in group 1, and not in group 2, which suggests some kind of adaptive response or of long-term recovery following continuous exposure.
