この研究は、突然変異原および発がん物質の細胞遺伝学的影響を最も敏感に検出する姉妹染色分体交換（SCE）アッセイを用いて、マイクロ波の潜在的な突然変異原性影響を調べた。マウスの骨髄細胞に、マイクロ波（2450MHz、入射電力密度20 mW/cm2、平均SAR21mW / g）のばく露を28日間与えた。ばく露群、擬似ばく露対照群、標準対照群でのSCE発生を比較した。結果として、ばく露群と対照群の間で、SCEの数に統計学的有意差は検出されなかった、と報告している。

A sister chromatid exchange assay was utilized to investigate potential mutagenic bioeffects of microwave (2450 MHz) radiation on mouse bone marrow cells.

| チャンバの詳細 | Environmental chamber lined with microwave absorber maintained at 22°C and 55 % humidity. |
| ばく露装置の詳細 | Animals kept in 2.54 cm thick Styrofoam cages / 5 cm x 8 cm x 10 cm with the long axis of the cage and the animal parallel to electric field. |
| Additional information | The cages were mounted in slots cut in a large Styrofoam sheet. The cages were located in a circular pattern and the animals were rotated around the circle of cages every 4 h. Control animals was kept in another enviromental chamber identical to the exposure chamber but the animals were not handled and remained in their home cages during the whole exposure period. |
No statistically significant differences in the numbers of sister chromatid exchanges (SCEs) were detected between the exposed animals and the control mice.
