Which is a dangerous radiological pollutant?

Options

A. `C^(14)`
B. `S^(35)`
C. `Sr^(90)`
D. `P^(32)`

Answer

**Step-by-Step Solution:**

1. **Understanding Radiological Pollutants**: Radiological pollutants are substances that emit radiation and can be harmful to living organisms and the environment. This type of pollution can arise from nuclear explosions, accidents, or the mining of radioactive ores.

2. **Identifying a Dangerous Radiological Pollutant**: Among the various radioactive isotopes, Strontium-90 (Sr-90) is identified as a dangerous radiological pollutant. It is a byproduct of nuclear fission and is released during nuclear explosions and from nuclear reactors.

3. **Mechanism of Harm**: Sr-90 is particularly harmful because it mimics calcium and accumulates in the bones of living organisms. This accumulation can lead to serious health issues, including cancer, as it damages genetic material within the bones and other tissues.

4. **Health Implications**: The presence of Sr-90 in the body can cause various health problems, including lung cancer and other forms of cancer due to its radioactive nature and the damage it inflicts on cellular structures.

5. **Conclusion**: Therefore, Strontium-90 is recognized as a dangerous radiological pollutant due to its ability to cause significant health risks, including cancer and potential death, through its accumulation in biological systems.
