Evaluation of Exposure to Radon Progeny During Closure of Inactive Uranium Mines

The National Institute for Occupational Safety and Health (NIOSH) received a request for a health hazard evaluation at abandoned uranium mines in several western states. Managers of a federal agency requested assistance in evaluating employee exposures to radon while constructing mine closures.

Reducing Radon Levels in Existing Homes: A Canadian Guide for Professional Contractors

The following guide released by Health Canada has been written to provide professional building contractors with information on radon mitigation techniques for existing houses in contact with soil. The guide is based on the best information currently available, and has been reviewed by a committee comprising stakeholders from the housing industry. This guide is not a substitute for building regulations currently in effect. It is the contractor’s responsibility to ensure that they comply with the applicable health, safety and building code standards.

Report to Congress: Radon in Drinking Water Regulations

As required by the Safe Drinking Water Act, the EPA's Office of Water has developed a proposed regulation to reduce radon in drinking water that has a multimedia mitigation option to reduce radon in indoor air.

Based on a National Academy of Science report, EPA estimates that radon in drinking water causes about 168 cancer deaths per year: 89% from lung cancer caused by breathing radon released to the indoor air from water and 11% from stomach cancer caused by consuming water containing radon.

Guide for Radon Measurements in Public Buildings

This document is intended for persons and organizations intending to carry out radon measurements in public buildings. These buildings, considered dwellings, have a high occupancy rate and/or residency period for members of the public. The types of buildings include hospitals,
schools, long-term care residences and correctional facilities.

The purpose of the testing is to evaluate radon levels in order to determine the need for remedial
action to protect the dwelling residents. Occupational exposure of workers to radon is addressed separately through existing guidelines orregulations such as the Canadian Guidelines for Management of Naturally Occurring RadioactiveMaterials (NORM) and the Canada Labour Code.

The scope of this document is limited to guidance regarding types of measurement devices,
device placement, measurement duration, and the interpretation of measurement results regarding
corrective action for health protection in public buildings and schools.

Cross Canada Survey of Radon Levels in Homes

Health Canada has published its final report on a two year cross-Canada survey of radon levels in homes. The results indicate that 6.9% of Canadians are living in homes with radon levels above the national guideline. Though some provinces have higher incidences of high radon levels, every province has a significant number of homes with radon concentrations above the guideline.

Fact Sheet on Radon's Cancer Risks

The CMA has joined forces with Health Canada to remind Canadians - and their physicians - that the cancer risk posed by household radon gas is particularly acute for smokers.

"Almost 90% of lung cancer deaths are caused by smoking," says a new fact sheet designed for physicians to distribute to patients. "Radon exposure is linked to approximately 10% of lung cancers in Canada and is the second leading cause of lung cancer for smokers."

The connection between cancer and radon - a gas produced naturally as uranium breaks down, which then seeps into houses - is well known. However, many people are unaware that smokers living in a high-radon environment have a one-in-three chance of developing lung cancer, compared with a one-in-20 rate for non-smokers.
