A compact THz Free Electron Laser (FEL) isbeing used to perform irradiation ofbiological samples to investigate possiblegenotoxic effects. In order to evaluate theexact radiation dose absorbed by the singlecomponents of the samples it is necessaryto study the optical properties of thesamples, separating the contributions tothe radiation attenuation coefficientcoming from absorption and from diffusion.Spectroscopic measurements have beenperformed on different biological samples, comparing the experimental results withtheoretical models.
一台紧凑型太赫兹自由电子激光（FEL）正用于对生物样品进行辐照，以研究可能的遗传毒性效应。为了评估样品单个成分吸收的精确辐射剂量，有必要研究样品的光学特性，区分吸收和扩散对辐射衰减系数的贡献。已对不同生物样品进行了光谱测量，并将实验结果与理论模型进行了比较。
