Authors: Karim Moutchou Institution: Medical Student, Fez Faculty of Medicine and Pharmacy Juntendo university hospital From the 6th to 11th of August 2019, I participated in a surgical internship program at the department of urology at the Juntendo University in Tokyo. There, I had an opportunity to observe urological surgeries operated with the latest medical technologies in the world. Juntendo hospital was founded in 1838 and was the first Japanese hospital in history to adopt modernized medicine. When I was walking around the hospital while being guided by residents of Juntendo hospital, it felt to me like I was in an institution from science fiction movies. This was my first time to see

It has been reported that the effects of obesity, smoking, and drinking on our bodies are comparable to being exposed to several hundred millisieverts of radiation. Besides, controlling body weight, blood pressure, cholesterol, and blood sugar levels is key to preventing lifestyle-related diseases. When it comes to lifestyle modification, people often try to manage it through individual efforts, such as moderation, dietary restrictions, and exercise. However, it is often challenging to achieve lifestyle modification through self-

A balanced lifestyle is important for maintaining health The extent of the exposure dose determines the impact of radiation on health, which means that you will not have cancer for sure even when you are exposed to radiation to some extent. When the total radiation exposure exceeds approximately 100 millisieverts, a larger amount of exposure leads to a higher risk of developing cancer. On the other hand, the adverse health effects of smoking and drinking alcohol are comparable to being exposed to several hundred millisieverts of radiation. Thus, a good lifestyle is crucial for maintaining health. There are four condition

The reasons for 1 millisievert as the annual dose limit for the general public The extent of the exposure dose determines the impact of radiation on health. It has been shown that a high level of radiation exposure (exceeding 100 millisieverts) increases the risk of death from cancer. On the other hand, it remains unknown whether radiation exposure below 100 millisieverts contributes to death from cancer. Even if it does, lifestyle factors (including obesity, smoking, and drinking) are considered to have a more significant impact on our health than radiation exposure below 100 millisieverts. However, this does not mean w
