…LET values are large for charged particles with large electric charge and mass, and small for gamma rays and high-energy electron beams. The chemical and biological effects of radiation (radiation biological effects) may vary depending on the LET of the radiation, even if the amount of energy absorbed by the substance is the same. This is called the LET effect. This is thought to be because the geometric distribution of chemical species produced in a substance by the absorption of radiation energy changes depending on the LET. … *Some of the terminology that refers to the "LET effect" is listed below.

…LET値は電荷や質量の大きい荷電粒子では大きく,γ線や高エネルギー電子線では小さい。 放射線のもたらす化学効果や生物効果(放射線生物効果)が,物質によって吸収されるエネルギー量は同じでも,放射線のLETの相違によって変化する場合があり,これをLET効果と呼んでいる。これは,放射線エネルギーの吸収によって物質中に生じる化学種の幾何学的分布がLETによって変わるためと考えられている。… ※「LET 効果」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
