Smoker’s lungs: The most powerful source of radiation in the human body

   Smoking is harmful, it is a common topic. But what many people don’t know is that smoking causes a powerful amount of radiation in the human body, and the radiation comes from the smoker’s lungs.
  Why does smoking have radiation?
   Take the usual chest X-rays as an example, an X-ray is irradiated by 100 microsieverts (radiation unit), and the lungs of smokers receive an average of 160,000 microsieverts of radiation every year. In other words, the smoker took the equivalent of 1600 chest X-rays in one year.
   According to the Tencent video “The World’s Most Radiated Place”, the annual radiation dose received by smokers’ lungs far exceeds that of a CT scan (7,000 microsieverts), and it is more than 3 years after the Fukushima nuclear explosion in Japan. The residual dose of astronauts is more than the radiation dose (80,000 microsieverts) received by astronauts in outer space for 6 months.
   How does smoking cause radiation? This is because there is a radioactive element, polonium, in the smoke produced by the burning of tobacco. When you puff in the mist, these polonium elements will enter the lungs to “make a home”. With each cigarette smoked, polonium radiates a little more to the smoker’s lungs. Over the years, a smoker’s lungs act like a “radiation bomb”. In lung cancer patients, polonium-210 is the unknown “murderer”. Polonium-210 can also accumulate in the liver and blood, leading to leukemia to a certain extent.
  Will family members be irradiated?
   Many people will be very worried: if there are smokers at home, will their family members be irradiated? Don’t be too nervous. Although polonium-210 is the alpha ray with the strongest ionizing ability, because it ionizes first in the smoker’s lungs, the energy loss is huge, so the ability to pass through the body and skin again will become very poor. Basically, Can’t wear it. Therefore, the smoker’s lungs, as the strongest radiation source, only radiate to himself and will not pose a threat to those around him.
   However, second-hand smoke that remains indoors also contains radioactive substances that can enter the body with breathing. At present, the effective way is to not smoke, which is an effective means to protect the health of yourself and your family.
  Try the 5-Day Smoking Cessation Method
   Day 1: Preparatory stage. People who quit smoking should learn about the harm of smoking, the benefits of quitting smoking, the mechanism of smoking addiction, etc. through various means on this day.
   Day 2: Ritualized quitting is a day where people need to mentally prepare themselves and ask themselves if they are ready to cut ties with cigarettes forever. If you are hesitant, you need to repeat or strengthen the first step; if the answer is very yes, throw away all the crushed cigarettes, lighters and smoking accessories.
   Days 3 and 4: Withdrawal symptoms A few days after stopping smoking, some physical and psychological reactions will occur, such as drowsiness, insomnia, dry mouth, cough and phlegm, dizziness, anxiety, depression, general weakness, etc. Some active means to help us resist withdrawal symptoms, such as drinking water, washing face with cold water, drinking tea, doing housework, exercising, etc.
   Day 5: Summary of experience At this point, you have already fought a round of smoking addiction. You need to constantly summarize your experience, find out the difficulty of quitting smoking, and then “prescribe the right medicine”. At the same time, try to put yourself in a smoking environment as little as possible, and resolutely refuse to give cigarettes from others. Withdrawal symptoms will gradually decrease between 1 and 2 weeks, until they disappear completely after 3 weeks.

   Some patients are worried that the installation of a heart stent will affect the MRI examination, and they believe that the metal heart stent may be displaced in a strong magnetic field, and the heat generated by electromagnetic induction will burn blood vessels. This worry is unnecessary.
   The MRI commonly used in clinical practice has a magnetic field strength of 3.0T or 1.5T. Under the magnetic field of 3.0T field strength, the position of the heart stent will not move. Therefore, even if the stent is implanted immediately after the MRI, it is feasible.
   In addition, in a magnetic field with a field strength of 3.0T, the temperature rise of the stent due to current conduction will theoretically not exceed 2.6℃-4.7℃, and under the continuous scouring of blood flow in the blood vessel, the temperature rise of the stent is almost negligible. Excluding.
