Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

Cobalt-57 and Cadmium-109 are associated with what?

1. Lead-based paint inspection

2. Risk assessment

3. Abatement

4. Interim control

The correct answer is: Risk assessment

Cobalt-57 and Cadmium-109 are radioactive isotopes commonly used in analytical procedures to assess the presence of lead in dust and paint samples. In the context of risk assessment, these isotopes provide crucial information on lead levels within various environments. This is essential when determining the potential risk pose by lead exposure in residential settings, especially those with young children or pregnant women. Using these isotopes aids in quantifying lead content, which is vital for any effective risk assessment strategy. Knowing the presence and levels of lead supports the development of appropriate interventions to reduce exposure and improve safety. Therefore, the association of Cobalt-57 and Cadmium-109 with risk assessment underscores their role in evaluating lead hazards in environments where lead-based paint may be present.
