摘要

初步研究了人肺癌细胞与毫米波电磁波的相互作用。在不同暴露时间下，通过75-110 GHz (w波段)的频率扫描进行体外辐照。对不同曝光时间下反射信号的频谱进行了分析比较。此外，对显微镜成像获得的细胞群进行了统计分析。观察到以下效应:1)辐照下种群平均大小缩小;2)大细胞群(“怪物”)的出现;3)形成多核(多倍体)细胞;4)功率吸收对暴露时间的依赖性。

Millimeter waves non-thermal effect on human lung cancer cells

Preliminary investigation of human lung cancer cells' interaction with millimeter wavelength electromagnetic waves was carried out. The irradiation was performed in vitro by sweeping in frequency in the range 75–110 GHz (W-band), for different exposition times. Frequency spectra of the reflected signal were analyzed and compared for different exposure times. Also, a statistical analysis of the cell populations obtained by microscope imaging was performed. The following effects were observed: 1) retraction of the mean size of the population under irradiation; 2) appearance of the population of large cells (“monsters”); 3) formation of multi-nuclear (polyploidy) cells; 4) dependence of power absorption on the exposition time.
