ばく露装置
ばく露の発生源/構造
ばく露装置の詳細 The exposure system consisted of a cylindrical parallel plate with mice restrained motionless in clear Perspex tubes arranged radially around the antenna [Finnie et al., 2001].
Sham exposure A sham exposure was conducted.
Additional information A non-exposed, freely moving, cage control group without handling was also included.

研究の主なアウトカム(著者による)

No albumin extravasation was found in brains of exposed or control (sham exposed and freely moving caged) mice. By contrast, in the positive control mice there was substantial albumin extravasation.
It appears that exposure of the developing mouse brain to mobile phone-type radiofrequency electromagnetic fields does not produce any perturbations of blood-brain barrier integrity.
