Though the absorbed energy is far below the existing safety limit, the cell in experiment shows a growth inhibition. This phenomenon combined with the numerical results suggests that the safety assessment based on energy absorption is questionable.

• 虽然人体从单个脉冲吸收的能量远低于用比吸收能定义的安全标准,但这种剂量的照射在离体培养的人肝细胞(L 02)上却产生了明显的生物学效应,这意味着比吸收能难以作为人员安全评估标准。
