Mr. Liao's mother recently had an unfortunate tumor and needed a CT scan. Because the elderly mobility, difficult to cooperate, the examination doctor needs Mr. Liao help, but also let him wear a very heavy clothes.
Hearing that the clothes can protect against radiation, Mr. Liao is quite confused: his wife is also pregnant through radiation clothing, neither thick nor heavy, how to the examination room, medical radiation clothing is so much heavier? Is it possible that pregnant women radiation clothing is "cottage"?
Anti-ionizing radiation, clothing is very heavyMany people are not very clear about the concept of radiation. In fact, radiation can be divided into ionizing radiation and electromagnetic radiation. News events in the appalling nuclear accident, may harm the human body is mainly ionizing radiation; and people's daily worries about microwave ovens, cell phones, computers and other electrical appliances produce mainly electromagnetic radiation.
The application of X-rays, such as fluoroscopy, X-ray, CT, etc., will produce ionizing radiation, which will have a certain effect on the examinee.
The magnitude of the harm done by X-rays to the human body is mainly related to the distance, contact time, exposure dose and other factors. Clinically, the actual radiation time of X-ray examination is very short, and the possibility of causing cancer is very small.
In order to minimize radiation damage during medical examinations, a variety of radiation-protective clothing has been made, such as the lead suit worn by the doctor for Mr. Liao's mother, described above. Filled with multiple layers of protective material set according to the protection requirements, the lead suit has excellent radiation protection and is also very heavy, with one piece weighing 10 to 15 kilograms.
anti-electromagnetic radiation, the clothes are very lightAs long as the temperature itself is greater than absolute zero of the object, can emit electromagnetic radiation, and the world does not exist in the temperature is equal to or below absolute zero of the object - therefore, all objects at all times in the electromagnetic radiation.
With the massive use of induction cookers, cell phones, and computers in modern homes, people have developed some concerns about the dangers of electromagnetic radiation. In order to protect pregnant women and fetuses, people have designed radiation protective clothing for pregnant women. Maternity anti-radiation clothing sold on the market is generally lighter and may provide some protection against electromagnetic radiation, but it is useless against ionizing radiation.
From a practical point of view, the radiation protection clothing for pregnant women made of lead clothing is also unrealistic - wearing clothes weighing up to 15 kilograms all day long, not to mention the pregnant women, that is, the young and strong young man will not be able to stand.
What is the use of anti-radiation clothing for pregnant women?Pregnancy radiation clothing, is in the fabric to add metal - metal has a conductive, can shield part of the electromagnetic radiation. The more metal contained in the fabric, the better its radiation protection performance. Of course, in the clothes of the collar, cuffs and other openings, electromagnetic waves can easily invade, its shielding effect is very weak.
On the other hand, there are no relevant clinical reports proving that electromagnetic radiation can be harmful to a woman's pregnancy. Therefore, so far it is difficult to say that pregnant women wearing radiation protection clothing can have much effect.
The idea of being prepared is understandable. If you want to seek a peace of mind, buy a radiation suit to wear there is no harm. But instead of spending money to buy sunscreen clothing, it would be better to have less contact with some sources of radiation and minimize the use of computer time to the actual.
