Which of the following is a short term effect of radioactive radiation on humans?
A
Nausea and vomitting
B
Mutation
C
Cancer
D
Foetus defect
Explanation: 

Detailed explanation-1: -A very high level of radiation exposure delivered over a short period of time can cause symptoms such as nausea and vomiting within hours and can sometimes result in death over the following days or weeks. This is known as acute radiation syndrome, commonly known as “radiation sickness.”

Detailed explanation-2: -Being exposed to a lot of radiation over a short period of time, such as from a radiation emergency, can cause skin burns. It may also lead to acute radiation syndrome (ARS, or “radiation sickness"). The symptoms of ARS include headache and diarrhea. They usually start within hours.

Detailed explanation-3: -Symptoms of ARS may include nausea, vomiting, headache, and diarrhea. These symptoms start within minutes to days after the exposure, can last for minutes up to several days, and may come and go.

Detailed explanation-4: -In general, the higher the radiation dose absorbed, the greater the severity of symptoms and the more rapid the onset of vomiting. Radiation-induced vomiting occurs as a result of effects on the central nervous system and on the GI tract.

Detailed explanation-5: -Radiation exposure increases the risk of cancer throughout life, so continued follow-up of survivors is essential. Overall, survivors have a clear radiation-related excess risk of cancer, and people exposed as children have a higher risk of radiation-induced cancer than those exposed at older ages.
