Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
People have been warned about the dangers of excessive exposure to radiation during certain medical procedures. The most likely reason for this warning is that radiation exposure might
A
result in gene mutations and uncontrolled cell growth
B
cause the rejection of transplanted organs
C
increase body temperature by two to five degrees
D
prevent the transport of materials into cells
Explanation: 

Detailed explanation-1: -The purpose of a warning sign is to call attention to a radiation hazard. The marking must provide a warning that is intelligible even to a person who is unfamiliar with radiation protection.

Detailed explanation-2: -Computed tomography (CT) is the largest contributor to medical radiation dose patients receive. Typically, CT scans impart doses to organs that are 100 times higher than doses imparted by other lower dose modalities such as chest X-rays.

Detailed explanation-3: -Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.

Detailed explanation-4: -Exposure to large amounts of radiation over a short period of time can cause Acute Radiation Syndrome (ARS). If you have symptoms of ARS (skin burns, nausea, or vomiting) seek medical attention as soon as it is safe to leave your building or shelter.
