Thz poisoning
Webb26 mars 2024 · THz radiation reduces the degree of methylation, which is accompanied by changes in gene expression. Genes showing changes in expression in response to THz radiation are associated with cancer... WebbWe conducted a rabbit study to evaluate the safety profiles of THz scanning on eyes, at a tissue, cellular, structural and functional level. Eight animals (16 eyes) were analysed after excessive THz exposure (control, 1 h, 4 h, and 1 week after continuous 4-h exposure; THz frequency = 0.3 THz with continuous pulse generated at 40 µW).
