Explanation: A) If the dose of radiation is large enough (generally over 1.0 Gy or 100 rads, whole body), the resultant signs and symptoms that comprise these short-term effects are collectively known as acute radiation syndrome (ARS).
B) If the dose of radiation is large enough (generally over 1.0 Gy or 100 rads, whole body), the resultant signs and symptoms that comprise these short-term effects are collectively known as acute radiation syndrome (ARS).
C) If the dose of radiation is large enough (generally over 1.0 Gy or 100 rads, whole body), the resultant signs and symptoms that comprise these short-term effects are collectively known as acute radiation syndrome (ARS).
