REVIEW OF RADON AND THORON RESEARCH IN KENYA: 1997-2017

Area of Science:

• Environmental Science
• Radiological Health
• Geophysics

Background:

• Six research studies on radon and thoron in Kenya were conducted between 1997 and 2007.
• These studies were primarily small-scale, covering limited areas in Nairobi, Rift Valley, Coast, and Western regions.
• Findings were published in seven online journal articles.

Purpose of the Study:

• To identify high-risk areas for radon and thoron in Kenya.
• To increase awareness regarding the sources and health risks associated with indoor radon isotopes.
• To underscore the necessity for continued research on radon and thoron in Kenya.

Main Methods:

• Systematic review of seven existing online journal articles.
• Analysis of data from six prior research studies conducted between 1997 and 2007.
• Geographical mapping of reported radon and thoron levels across different Kenyan regions.

Main Results:

• Identification of specific areas within Nairobi, Rift Valley, Coast, and Western regions with elevated radon and thoron levels.
• Compilation of information on the primary sources of indoor radon and thoron.
• Assessment of the potential health risks posed by exposure to these radioactive isotopes in indoor environments.

Conclusions:

• Certain regions in Kenya exhibit high concentrations of radon and thoron, necessitating targeted monitoring.
• Increased public and scientific awareness of indoor radon/thoron risks is crucial for health protection.
• Further comprehensive research is essential to fully understand and mitigate the impact of radon and thoron in Kenya.
