Question

Which of the following isotopes is most dangerous Homo sapiens?

विकल्प

• Phosphorus-32

• Strontium-90

• caesium-137

• iodine-131

Answer 1

Phosphorus-32

Explanation:

The radioactive strontium-90 can cause bone abnormalities and diseases such as bone cancer. It produces high-energy beta radiation. Phosphors-32 emits high-intensity beta radiations as well, but they cannot pass through human skin. Caesium-137 (beta emitters) and iodine-131 (p and Y emitters) are similarly dangerous to human health, but not to the same extent as strontium-90, a long-lived radioactive element that cycles like calcium.
