I will strengthen my statement. Acute doses below 100 mSv have never been conclusively shown to cause or not cause harm or benefit. Certainly annual doses at that level also have not. The LD50/30 acute dose of radiation is 4,000 mSv. See chart I linked above. Certainly acute high doses are worse than the same dose spread over years or decades. I learned that in nuclear engineering school 20 years ago. Please don't assume I'm not grasping it.
