Hazards of nuclear radiation
Damage to the human body and possible symptoms
For people who are not exposed to radiation in their daily work, normal natural radiation per year: mainly because the radon radiation in the air is 1000-2000 microsieverts. Radiation <100 microsieverts has no effect on human body. For radiation-related workers, the annual radiation is less than or equal to 50.000 microsieverts. A one-time exposure to 4000 mSv will cause serious damage to human functions!
Radiation dose and human response list
Dose (Rum) Reaction
5~20 May have delayed reactions; may damage chromosomes
20~100 Temporary decrease in white blood cells
100~200 Mild radiation sickness within hours: vomiting diarrhea, fatigue; decreased resistance to infection.
200~300 Severe radiation sickness reaction the symptoms are the same as above this exposure is a lethal dose, and 10%~35%ofthe exposed people die after 30 days.The LD is(10~35)/30
300~400 Severe radiation sickness damage to bone marrow and intestine;LD is (50~70)/30
400~1000 Emergency,premature death;LD is(60~95)/30
1000~5000 Emergency, death within days; LD 100/10
