How much radiation (millisieverts) is involved in doing a head ct?

The radiation dose from a head CT is about 500 millisieverts, and the amount of radiation is like operating an X-ray screener in a subway or an airport, where you drill in and out of a channel 120 times in a row.

Being badly irradiated can lead to sterilization or serious lesions: different parts and organs have different thresholds for a single scan, mainly for the gonads, which require a very high level of safety! Because he is most likely to cause infertility conditions.

Please refer to the following list:
