What is the consequence of radium decay in relation to radon exposure?

Radium decay is a critical factor in the formation of radon gas, which is a byproduct of the decay process. Specifically, when radium isotopes decay, they produce radon as one of their decay products. This means that as radium continues to decay in the soil and surrounding materials, it leads to an increase in the concentration of radon gas in those areas.

Radon is a naturally occurring radioactive gas that can accumulate in homes, particularly in basements and lower levels due to its tendency to migrate from the soil into structures. Increased radon concentration poses health risks, particularly the potential for lung cancer with prolonged exposure.

Understanding this relationship is crucial for radon measurement technicians, as they need to assess radon levels accurately to ensure the safety of the living environment. Thus, the link between radium decay and the increase in radon concentration underpins the importance of monitoring and mitigating radon exposure, making this the correct response to the question.
