Radioactive substances can be inhaled through breathing, absorbed into the body through skin wounds and digestive tract, causing radiation in the body. Gamma rays can penetrate a certain distance and be absorbed by human body. Symptoms include fatigue, dizziness, insomnia, skin redness, ulcer, bleeding, alopecia, leukemia, vomiting, diarrhea and so on. Sometimes it will increase the incidence of cancer, distortion and hereditary diseases, affecting the health of generations. Generally speaking, the more radiation energy the body receives, the more serious the symptoms of radiation sickness, and the greater the risk of cancer and teratogenesis.

Radiation victims will vomit and feel weak in a short time, and then lose their hair until all their hair falls off, shortening their life span. Generally speaking, the DNA of cells in the body is destroyed, and cancer and leukemia are more common, and then they will die in a short time.

In case of nuclear radiation, hide first.

"In case of nuclear radiation, it is necessary to shorten the irradiation time as much as possible, stay away from radioactive sources, and pay special attention to shielding. When entering or leaving the nuclear pollution area, you should wear protective clothing and take a shower in time to remove nuclear pollution. " Chief physician Yang Yuhua, an expert in radiation medicine at Guangdong Institute of Occupational Disease Prevention and Control, stressed that in the event of a nuclear accident or radiation accident, especially when radioactive substances are released into the atmosphere, the general protection principle is "both internal and external prevention". First, the irradiation time should be shortened as much as possible; As far away from radioactive sources as possible; Pay attention to shielding, and use lead plate, steel plate or wall to block or reduce the irradiation intensity. "When radioactive substances are released into the atmosphere to form dust, they should enter the building in time, close the doors and windows and the ventilation system, and avoid poorly shielded parts such as doors and windows."

Secondly, avoid eating, reduce absorption, increase excretion, and avoid staying in polluted areas. Eliminate pollution and reduce the chances of people being polluted. "If a nuclear accident releases radioactive iodine, you should take stable iodine tablets as soon as possible under the guidance of a doctor. The recommended dose for adults is 100 mg iodine, and children and infants should reduce it appropriately, but those who are allergic to iodine or have a history of thyroid should use it with caution. "

At the same time, be sure to stay away from nuclear radiation. We should be alert to the five senses when entering an area where the air is seriously polluted by radioactive substances. For example, cover your nose and mouth with handkerchiefs, towels and cloth to reduce the inhalation of radioactive substances. Wearing hats, headscarves, glasses, raincoats, gloves and boots can help reduce radioactive pollution on the body surface. Pay special attention not to eat contaminated water, food, etc.

If the accident is serious and residents need to evacuate from the polluted area, they should obey the orders of the relevant departments and evacuate to a safe place in an organized and orderly manner. Personnel evacuated from polluted areas should take off contaminated clothes, shoes, hats, etc. Used for storage, monitoring and processing. The best way to clean up people who have been or are suspected of being contaminated by radioactivity is to take a bath.

Here's to health!
