Exhibit 9
How Radiation Affects Our Body?

How radiation affects our body?

Inside our body, a particular radioactive element by virtue of its chemical property tends to accumulate in a certain organ (critical organ). For example, radioactive strontium may concentrate in the bones because it is chemically similar to calcium.

The time required for the radioactive element in the body to be reduced to half its original amount is called the biological half-life.

The more important radioactive elements that affect our body are shown below alongside their critical organs.
