If the dose of radiation exceeds a certain threshold level, then it can produce acute effects, such as skin redness, hair loss, radiation burns, and acute radiation syndrome (ARS1).
Infrared radiation heats up the pit membrane tissue, and TRPA1 channels open when a threshold temperature is reached, allowing ions to flow into the nerve cells and triggering an electrical signal.
红外线使窝器膜组织升温，当达到阈值后TRPA 1通路打开，离子流入神经细胞并催发电信号。

The results show: pulse power density from CO2 laser reaches air breakdown threshold through thrice reflecting focus system, and plasma radiation phenomena is observed in the experiment.
