Hello, I need to ask two questions. 1. Excuse me, is working in the monitoring room harmful to the body? 2. As an airport security inspector, is this job radioactive?

Question 1: The radiation generated by electronic products such as computers in the control room is non-ionizing radiation. Because the energy of this radiation is too low, it has no harmful effect on the human body, so there is radiation, but it has no effect on the body.

Question 2: The airport security instrument uses X-rays, and the radiation generated is ionizing radiation, which is harmful to human body. But if the dose of this radiation is very small, we also think that this radiation will not have harmful effects on the body.

This is because a small amount of ionizing radiation fills every corner of the world, and the average person receives 2400usv of ionizing radiation every year. The statistics of the US Centers for Disease Control and Prevention on the extra radiation received by security personnel at American airports prove that the extra radiation received by security personnel is between 100 ~ 600 USV every year, with an average of 120 USV.

In contrast, you will find that as a security inspector, the radiation you receive from the security instrument is very small, and the radiation you receive after 20 years of security inspection is equivalent to the radiation that ordinary people receive in one year.

As for the tumor you said, I just want to say that even if he doesn't do security check, he will still grow a tumor. At present, the general attitude in the medical field is that ionizing radiation exceeding 100msv will have an impact on human carcinogenicity in a short time. That is to say, if he gets cancer because of the security check, he will have a certain probability of getting cancer if he has done the security check of 1000 in a short time (for example, half a year).
