[非熱的レベルのFM無線電波への慢性ばく露はショウジョウバエの突然変異を起こさない] med./bio.

Failure of chronic exposure to nonthermal FM radio waves to mutate Drosophila.

掲載誌: J Hered 1977; 68 (4): 257-258

この研究は、X染色体上に劣性致死遺伝子もつショウジョウバエを用いて、FMラジオ放送波へのばく露の影響を調べた。ハエは、98.5 MHz、50 kWの送信アンテナから300フィート離れた場所で、32週間飼育された。その場所の電界強度は0.3V / mであった。結果として、4,020時間の非熱的FMラジオ波ばく露されたばく露群と対照群の間に致死率の有意差はなかった、と報告している。

研究目的(著者による)

To assess whether radio waves used for transmissional purposes are a mutagenic hazard, an experiment was designed in which Drosophila were chronically exposed to radio waves.

詳細情報

A mating scheme was utilized in which the X chromosome to be treated is passed only from mother to daughter, and thus this X chromosome could accumulate lethals that would otherwise be fatal in the male.
