Which tissue type will experience fewer biological effects when exposed to radiation?

• A. Highly radiosensitive tissues
• B. Radioresistant tissues
• C. Soft tissues
• D. Rapidly dividing tissues

Answer: (B)

Radioresistant tissues are known for their ability to withstand radiation exposure with fewer biological effects compared to other tissue types. These tissues have a lower proliferation rate and are generally more robust in terms of cellular structure and repair mechanisms. Examples of radioresistant tissues include muscle and nerve tissues, which are less affected by ionizing radiation due to their slower cell division rates. In contrast, highly radiosensitive tissues, such as those involved in blood production or rapidly dividing cells, are more vulnerable to the damaging effects of radiation. Soft tissues can vary in their sensitivity but tend to be more affected than radioresistant tissues. Rapidly dividing tissues, such as those in the bone marrow or the gastrointestinal lining, are also particularly susceptible to radiation, leading to greater biological effects from exposure. Therefore, radioresistant tissues clearly demonstrate fewer biological effects when exposed to radiation.
