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).

如果辐射剂量超过一定的阈值水平，那么它可以产生，如皮肤发红，脱发，辐射烧伤和和急性辐射综合症(ARS1)等急性影响。

Diagnosis should include history of exposure to radiation, which dose exceed the dose threshold, and typical clinical characteristics.

诊断时应有明确的射线接触史，并超过剂量阈值，出现典型的临床特征。
