A typical radon test kit Fluctuation of ambient air radon concentration over one week, measured in a laboratory. The first step in mitigation is testing. No level of radiation is considered completely safe, but as it cannot be eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
To achieve these aims, WHO has formed a network of key partner agencies from some 40 Member States. This network is the basis for the WHO International Radon Project which was launched in 2005. Working groups will collect and analyse information on radon risk, radon policies, radon mitigation and prevention as well as risk communication.
The Philippine Council for Agriculture, Aquatic, and Natural Resources Research and Development (PCAARRD) is a council of the Department of Science and Technology of the Philippines government. The council aims to help national research and development efforts in agriculture, forestry, and natural resources of the Philippines. It does so by ...
Radon is measured in picocuries per liter of air (pCi/L) or becquerel per cubic meter (Bq m-3). Both are measurements of radioactivity. The World Health Organization (WHO) sets the ideal indoor radon levels at 100 Bq/m-3. [97] In the United States, it is recommend to fix homes with radon levels at or above 4 pCi/L.
Installing a radon sump system in the basement; Sealing floors and walls (not a stand-alone solution); and; Installing a positive pressurization or positive supply ventilation system. The half-life for radon is 3.8 days, indicating that once the source is removed, the hazard will be greatly reduced within approximately one month (seven half-lives).
Natural radon concentrations in the Earth's atmosphere are so low that radon-rich water in contact with the atmosphere will continually lose radon by volatilization. Hence, ground water has a higher concentration of 222 Rn than surface water , because radon is continuously produced by radioactive decay of 226 Ra present in rocks.
The Philippines thus developed the National Climate Change Action Plan (NCCAP) to achieve country-driven programs on adaptation and mitigation. [10] Based on technical evaluations and discussions with government organisations and stakeholders, the NCCAP sets the nation's plan for adaptation and mitigation from 2011–2028.
The National Disaster Risk Reduction and Management Council (NDRRMC), formerly known as the National Disaster Coordinating Council (NDCC) until August 2011, is a working group of various government, non-government, civil sector and private sector organizations of the Government of the Republic of the Philippines established on June 11, 1978 by Presidential Decree 1566.
