Question

When radiation is absorbed in tissue the ionization and excitation energy result in which of the following:

A) Increased density of tissue
B) Cellular damage
C) Cooling effect
D) Antibody production

Answer 1

Absorbed radiation in tissue leads to cellular damage due to the ionizing effects on molecules within cells.

Step-by-step explanation:

When radiation is absorbed in tissue, the ionization and excitation energy result in cellular damage. This occurs because radiation can break chemical bonds or ionize molecules within the cells, leading to highly reactive ions and molecular fragments. These can cause serious malfunctions in cell processes and impair the organism's repair mechanisms, potentially causing illness or death.
