Maps of average radon levels in houses are available, to assist in planning mitigation measures. [8] While high uranium in the soil/rock under a house does not always lead to a high radon level in air, a positive correlation between the uranium content of the soil and the radon level in air can be seen.
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.
U.S. Route 1 Bypass (US 1 Byp.) is a 4.3-mile-long (6.9 km) bypass of U.S. Route 1 in Portsmouth, New Hampshire and Kittery, Maine.Most of its north section, northeast of the Portsmouth Traffic Circle where it meets the Blue Star Turnpike (Interstate 95 or I-95) and Spaulding Turnpike, is built to rudimentary freeway standards, with no cross traffic but driveway access.

Though it does not directly connect to SR 236 as signed, the two routes are connected by ...
The public needs to be aware of radon risks and the means to reduce and prevent these." [2] In 1996 [citation needed], WHO published a report containing several conclusions and recommendations covering the scientific understanding of radon risk and the need for countries to take action in the areas of risk management and risk communication.
Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics and basements.

This is a list of Superfund sites in Maine designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.
