The IAEA helps countries develop national infrastructure for nuclear power. This includes assistance with all of the following EXCEPT:
Answer:
Providing direct construction financing and operating the plants.
The IAEA provides the policy and safety guidance; actual financing and operation of nuclear power plants are the responsibility of the member state or commercial entities.
2
What is the name of the official title of the IAEA's administrative head and chief executive officer?
Answer:
The Director-General

The **IAEA Code of Conduct on the Safety and Security of Radioactive Sources** is designed to mitigate the risk that radioactive sources could be used for:
Answer:
Malicious acts or cause harm through accidents.
Radioactive sources, though essential for many peaceful uses, can be dangerous if lost, stolen, or improperly handled.
4
The IAEA's technical cooperation work in the marine environment focuses on using nuclear techniques to study:
Answer:
Ocean acidification, marine pollution, and harmful algal blooms.
Isotope tracing and other nuclear techniques are used to track pollutants and understand complex marine processes.
5
What is the primary method used by the IAEA Safeguards inspectors to verify that nuclear material is not being diverted?
Answer:
Independent verification through on-site inspections, material accountancy, and surveillance technologies.
Verification is a blend of technology and inspection to detect any discrepancies in a state's declared nuclear inventory.
6
Which of the following is an example of a peaceful nuclear application supported by the IAEA in agriculture?
Answer:
Developing new crop varieties that are disease-resistant or climate-resilient through mutation breeding.

10
The IAEA promotes the use of nuclear techniques in **hydrology** for what main purpose?
Answer:
Mapping groundwater resources and studying water pollution.
Isotope hydrology uses stable and radioactive isotopes to trace the origin, movement, and age of water, which is critical for sustainable water management.
