Radiosensitive tissues include:

Radiosensitive tissues include:

• A. Nerve tissue
• B. Blood forming organs, reproductive organs, lymphocytes
• C. Muscle tissue
• D. Bone

Answer: (B)

Radiosensitivity is greatest in tissues with high cell turnover and cells that are less differentiated. Cells that are rapidly dividing have DNA that's more exposed to radiation effects, and they have less time to repair damage before dividing again. Nerve tissue and muscle tissue divide very slowly, so they are relatively radioresistant. Bone itself isn’t the most radiosensitive tissue, because the sensitive part is the bone marrow inside bones, and as a tissue, bone is not as vulnerable as the hematopoietic and lymphoid components. Among the options, blood-forming organs (bone marrow and related hematopoietic tissue), reproductive organs (gonads), and lymphocytes are classic examples of highly radiosensitive tissues due to their rapid proliferation and presence of primitive or immature cells. Radiation can quickly disrupt blood cell production, affect fertility, and cause a drop in lymphocytes. So the best choice is the one that lists blood-forming organs, reproductive organs, and lymphocytes.
