Nuclear radiation and symptoms

Human beings have been exposed to natural sources of ionizing radiation throughout history, including cosmic rays and radiation produced by radionuclides on the earth. The collective radiation dose to humans comes mainly from natural background radiation and medical treatment.

At present, the three principles of radiation protection generally adopted in the world are: the legitimacy of practice, the optimization of the protection level and the personal dose limit. International basic safety standards stipulate that the personal dose limit for public exposure is 1 mSv per year, while the personal dose limit for occupational exposure is 20 mSv per year.

Nuclear radiation symptoms

Nausea and vomiting are the earliest symptoms of typical radiation sickness. The more radiation dose, the earlier these symptoms appear. Radiation can damage hair follicles. Sometimes, this hair loss is permanent. Radiation sickness can cause oral ulcers.

More symptoms include: spontaneous bleeding; hemorrhagic diarrhea; skin loss; severe fatigue; infection.

Nuclear radiation may cause major diseases: leukemia, thyroid cancer, multiple myeloma, benign and unexplained tumors.
