Can the human body security check instrument be used with confidence?
Normally, don’t worry about the kind of hand-held metal detector we see at the airport or railway station. After all, that kind of detector uses the principle of magnetic induction, so a sweep will not endanger the health of the pregnant mother or the fetus.
However, it is really necessary to keep an eye on it. For example, according to the news that broke out a long time ago, Shuangliu Airport has introduced a new type of human body security check device. The [frenzied] part of this security check device is called the “weak photon” that does not know what to say. It uses X-rays.
Can pregnant mothers pass this kind of security check device?
Pregnant mothers who often watch the director’s nagging all know that X-ray is a kind of [ionizing radiation], which is harmful to human body. Pregnant mothers should try their best to avoid it.
However, the [radiation] of mobile phones, televisions and wireless networks is [non-ionizing radiation], and no threat to health has been found so far.
Although the data released by the product show that the radiation dose for a single inspection is far lower than the limit of 10mSv, which is generally considered harmful to human body, only 0.05 ~ 0.2 Sv; However, it is not clear whether and how much damage the instrument will cause.
After all, even for healthy people, medical X-ray examination and CT examination are necessary to diagnose diseases that may be more harmful to health after weighing the pros and cons. There is a potential threat to public health that requires more caution when X-ray scans are performed indiscriminately for all people. However, a medical examination will produce about 1,000 times as much ionizing radiation as passing such a security check.
Perhaps I was not sure. At that time, the security personnel at Shuangliu Airport specially opened the security check channel for the old, the young, the pregnant and the disabled, so that the pregnant mother had a chance to avoid the robbery. Officials have also taken swift and forceful measures. The Environmental Protection Bureau has demanded [immediate removal] of all human security screening devices.
Affected, can children still have them?
If you really pass the X-ray security check, or if you are close to such a security check device, do you need to worry?
The director’s suggestion is: Don’t worry if you are pregnant, look at it first; Don’t worry if you are not pregnant yet, just follow the plan.
At present, research believes that the minimum threshold for X-ray to affect the fetus (embryo) is 10 mSv. Exceeding this value may cause cancer, and even higher, reaching more than 100. Depending on the period, it may cause injuries such as abortion, malformation, brain growth retardation, etc.
| 对胎儿影响 | 接受照射时期 | 剂量阈值(mSv) |
| 胎儿死亡(流产) | 着床前期(受精～9 日) | 100 |
| 畸形 | 器官形成期 (2～8 周) | 100 |
| 大脑发育迟缓 | 胎儿期 (8～25 周) | 120 |
| 癌症风险 | 全期间 | 10 |
You see, even if you were forced to take X-rays from the security check device, you don’t have to worry about the baby now.
Is the mandatory security check affecting pregnancy preparation?
Security screening devices have also affected more people who are planning to give birth. Do they have to wait another three months?
Parents-to-be who are preparing for pregnancy need not panic either.
The cycle of male sperm production is about three months, and mature sperm will survive in the body for two weeks. The irradiated mature sperm, whether ejaculated or not, will disappear after two weeks.
When a girl is born, she carries all the eggs in her life. It is only a matter of time before what matures and ovulates.
As we mentioned earlier, sperm and eggs in the body are irradiated by the security check device, and their X-ray intensity is about 1/1,000 of that of medical examination. However, a single X-ray or CT examination will not affect the pregnancy preparation plan, let alone worry about passing through the security check device.
Is how safe for security checks?
Finally, let’s talk about how pregnant mothers and pregnant couples should safely undergo security checks in this three-step and one-post country.
1. Recognition of ionizing radiation markers
You may have remembered that if a place is pasted with this yellow triangle sign, it indicates that there is ionizing radiation nearby. If there is concern in your heart, try to stay away, do not stay, and leave as soon as possible.
Like the kind of security check device with leather curtain, it is detected by X-ray, which will not adversely affect pregnant women. However, if you feel uneasy, pass as soon as possible, don’t stay, don’t stand facing the leather curtain.
In fact, it is not a big deal for what to take such a low dose of X-rays at such a time. However, what is more difficult for parents is that this time the [weak photon security detector] specially arranged the sign in an inconspicuous position, which is also very, very, very excessive.
STEP 2 Accept Metal Detection Scanning with Confidence
As mentioned at the beginning of our article, the hand-held metal detector, which sweeps all over the body, has no ionizing radiation and is harmless to the body. It can be checked with confidence.
The metal detection door that people have to pass through is similar. It does not bring [ionizing radiation] and can pass through with confidence.
They use the principle of magnetic induction. Induction cookers, acoustics and telephones commonly used in our life all use this principle and need not worry about harmful health.
Well, do you understand? If you understand, you can go out and play with confidence.
