List of Questions19 questions
- Question 1
- Stable isotopes do not decay and do not produce radiation, while unstable isotopes readily decay and give off subatomic particles and electromagnetic energy.
- Stable isotopes can only exist in nature, while unstable isotopes are artificially produced in labs.
- Stable isotopes are used in medicine, while unstable isotopes are not.
- Stable isotopes have a longer half-life compared to unstable isotopes.
- Question 2
- By capturing subatomic particles emitted by the radioisotope
- By measuring the amount of radiation it gives off
- By using radioactive iodine-131 for tracking purposes
- By assessing the level of stability of the radioisotope
- Question 3
- To diagnose and treat thyroid function
- To scan various organs like the brain, heart, and lungs
- To test for thyroid activity
- To measure blood volume in the body
- Question 4
- It is taken up only by certain tissues in the body.
- It is used to capture subatomic particles emitted by the thyroid gland.
- It is administered to the patient to measure the amount of radioactivity in the thyroid gland.
- It is inhaled into the body and circulates through the bloodstream.
- Question 5
- About 24 years
- 1 month
- 8 days
- 12 years
- Question 6
- To track the distribution of radioisotopes in the body
- To diagnose and treat illness and diseases
- To assess organ function and bone growth
- To produce radiation for imaging techniques
- Question 7
- Stable and unstable
- Long-lived and short-lived
- Natural and artificial
- Common and rare
- Question 8
- Technetium
- Uranium
- Hydrogen
- Iodine
- Question 9
- The elimination of radiation from the body
- The production of stable isotopes in the body
- Increased organ function and bone growth
- Damage to human cells and potential cancer development
- Question 10
- Diagnosing hyperthyroidism and hypothyroidism
- Testing for bone growth
- Treating lung diseases
- Evaluating liver function
- Question 11
- They are formed naturally in the body.
- They produce stable isotopes during decay.
- They have short half-lives and typically decay before causing damage to the patient's body.
- They have long half-lives and are used for long-term imaging.
