Applications using terahertz (THz) frequency radiation will inevitably lead to increased human exposure. The power density and specific absorption rate (SAR) simulations of thin skin at 0.45 THz show the bulk of the energy being absorbed in the upper stratum spinosum, and the maximal temperature rise is in the lower stratum spinosum. There are regions of SAR increase of 100% above the local average at the stratum spinosum/stratum basale boundary. The dead Stratum Corneum layer protects underlying tissues in thick skin. Reflection studies suggest that acute angles and the use of polarised incident radiation may enhance the assessment of diabetic neuropathy.
使用太赫兹（THz）频率辐射的应用将不可避免地导致人类暴露增加。对薄皮肤在0.45太赫兹下的功率密度和比吸收率（SAR）模拟显示，大部分能量被吸收在上层棘层，最大温度升高出现在下层棘层。在棘层/基底层边界处，SAR有高于局部平均值100%的增加区域。角质层死皮保护厚皮肤中的下层组织。反射研究表明，锐角和使用偏振入射辐射可能会增强对糖尿病神经病变的评估。
