Effect of high-power pulses of terahertz radiation on cell viability

We present the results of studying viability of human skin fibroblasts exposed to pulses of THz radiation with the peak intensity and electric field strength of 32 GW/cm2 and 3.5 MV/cm, respectively, for 90 minutes. Activation of the cascade of proapoptotic enzymes (not leading to cell apoptosis) and inhibition of the ROS action on cells were found.
