Is radiation harmful to the human body in daily life?

Radiation is always worried.
But in fact, it is not a terrible thing.
Everything is radiation body
Radiation is not a terrible thing. All objects in nature (naturally include us humans), as long as the temperature is above zero (-237.15 ° C), radiation will be emitted.
However, radiation belongs to radiation, but each other is different. According to the ability to ionize or not, radiation can be divided into non -ionized radiation and ionization radiation.
Non -ionizing radiation is a big family and is quite powerful. We are familiar with communication base stations, radio and television, mobile phones, microwave ovens, infrared remote controls, rainbow, ultraviolet rays, and thunder and lightning.
What makes everyone really feel scared, most of them are ionizing radiation. Ionizing radiation is good at "invisible". Due to excessive fear, many people mistakenly radiated non -electrical radiation as electrical radiation.
In fact, ionizing radiation is not nothing. With the development of technology, in the fields of medical, industry, agriculture, environment, security, aerospace, archeology, nuclear energy and other fields, ionizing radiation has also played a huge role in more and more.
A lot of contributions in the medical field
Since the epidemic of new coronary pneumonia, medical protection services have become tight supplies. You may not know that the time for ionizing radiation to shorten the sterilization of medical protection and sterilization from chemical methods from 7 to 14 days to 1 day.
According to relevant data from the International Atomic Energy Agency, about 12 million cubic meters of medical devices are disinfected by radical technology each year. More than 40%of all disposable medical devices produced in the world are sterilized by 40%. Most of the common disposable infusion, injection needle, and surgical equipment in the hospital are disinfected by radiation.
Not only medical disinfection, in fact, from the moment the nuclear science was discovered, ionizing radiation was applied to medicine. It can be used as a diagnostic method or a treatment tool, which is applied to many aspects such as imaging medicine, nuclear medicine, and radiation therapy.
The X -ray machines, CT machines, gamma knives, etc. we are familiar with are ionized radiation equipment. The more popular heavy ions now treat tumors, and it is also a rising star in the ionization radiation.
Make apples sweeter and make the flowers more glamorous
The application of ionizing radiation in the industrial field is even more widely used, including nuclear instruments, radioactive wells, industrial explorers, industrial irradiation and scientific research.
For example, the height of the liquid surface of the same specifications of the supermarket shelves is the same. How can this do? This is the credit of the nuclear radiation material.
In addition to measuring the height of the liquid surface of the material, ionizing radiation can also measure density, thickness, weight, etc. The amount of oil storage in the oil tank, the height of the cola liquid surface, the thickness of the printing paper/plastic board, the weight of the coal, and the compaction of the ground can be rely on this principle to complete the detection.
Roses and chrysanthemums are gorgeous and colorful, watermelon has no seeds, apples are red and sweet, pickled pepper and phoenix claws can be kept fresh for a long time, potato and garlic are not buds ... Among them, they have the effects of ionizing radiation radiation and breeding and radiation.
Using radiation to induce plant genetic material mutations, and then select good varieties for planting, you can get delicious, beautiful and high -yielded fruits and vegetables.
Food radiation preservation is a storage technology that uses X -rays, γ -rays, and high -energy electron beams generated by the radiation source, and a high -energy electron beam spray food generated by the accelerator to inhibit germination, delay mature, insecticidal sterilization, and does not destroy nutrients. Floid does not produce radioactive substances, and can be eaten with confidence.
Not only that, the mysteries of the history of Sanxingdui through the C-14 measurement method were explored, and the use of ray radical sterilization technology to eliminate mosquito and insects. Cleaning energy nuclear power to help carbon peaks/carbon neutralization ... These are also ionizing radiation credit.
Everyone understands it. The radiation is by our side. If it is used reasonably, it is not only terrible, but also useful.
Can I prevent computer radiation from computer radiation?
The beautiful lady who loves to use her computer always wants to remove the particles radiation by the computer. Is it really useful to do this?
Cleaning radiation particles is a related measure for nuclear radiation protection. After the nuclear explosion, the particles with nuclear radiation will spread, stained on people's faces and clothes. If they are not cleaned in time, they will cause continuous ionizing radiation damage to the human body. However, computer display radiation is only an electromagnetic wave, which does not spread radioactive substances, and there will be no radiation particles. Therefore, wash face is not effective for anti -computer radiation.
Can I still eat the buns of the subway security instrument?
Take the subway to work every morning. Can you eat the buns in the bag after the subway security inspection instrument? Will there be nuclear radiation?
The subway security checker is the transmission ability of X -rays to check whether there are dangerous items in luggage. The signal of X -ray after penetrating the item is used by the computer to form an image of the internal structure of the item, and then it is displayed in different colors to obtain the color images of the inspection items.
The X -ray energy in the security instrument is low and will not cause damage to the items. Just like the sun, the warm sunlight is shining on the body, but the light will not stay in the body. Therefore, although the buns of the security check instrument have passed the X -rays, the X -rays will not be left on it, nor will it change the characteristics of the buns, so you can eat it with confidence. In the same way, after everyone shoots X -rays, the rays will not stay in the body.
Is there any radiation riding an electric vehicle?
In the morning and evening peaks, the traffic jam was panicked, and I wanted to change a electric bicycle to ride, but I was worried about radiation inside. What should I do?Electric bicycles use batteries as energy sources. Through controllers, motors and other components, electrical energy is converted into mechanical energy to achieve car forward.The battery can be divided into one battery, which is a disposable battery that cannot be reused, such as carbon -zinc batteries, alkaline batteries, mercury batteries, lithium -ray batteries, etc.; The other is a secondary battery, which is a battery that can be charged and reused.Most of the electric bicycles use secondary batteries.Like us charging mobile phones and computers, but only how much charging is charged, there will be no nuclear radiation in the battery.
