EPA reports RadNet laboratory results in conventional units, as shown below with their international equivalents: Medium Conventional unit International SI unit Air Filter Curie (Ci) per cubic meter (m3) Becquerel (Bq) per cubic meter (m3) Precipitation and drinking water Curie (Ci) per liter (L)

The PAG Manual provides non-mandatory guidance for state, local and tribal governments to use at their own discretion when planning for and responding to a radiological emergency. If required by FEMA’s Radiological Emergency Preparedness (REP) Program to implement PAG Manual guidance, offsite

The Environmental Protection Agency’s authority to set site-specific standards for Yucca Mountain comes from the Energy Policy Act of 1992. However, two other laws have important roles leading up to that authority: the Nuclear Waste Policy Act of 1982, and the WIPP Land Withdrawal Act. The Nuclear

The Nuclear Regulatory Commission (NRC) has regulatory authority over storage and disposal of all commercially-generated nuclear wastes in the United States, as well as disposal of spent fuel and high-level wastes generated by the Department of Energy. The NRC implements its general radiation

The EPA is a member of several interdisciplinary radiological emergency response teams. Any one of these teams can be called upon to support a radiological emergency. Some of these teams are listed below. Federal Radiological Monitoring and Assessment Center (FRMAC): During a major radiological

Food in sealed containers, bottled water, sealed juice, unopened soda containers and any unspoiled food in your refrigerator or freezer will be safe to eat. Use a damp towel or cloth to wipe off cans, bottles, packaged foods, counters, plates, pots and utensils before using them. After use, seal

The Indoor Air Quality Tools for Schools (IAQ TfS) Program advocates proactive measures, and the majority of the recommendations in the IAQ TfS Action Kit are either low cost or no cost. These low- and no-cost actions will help to minimize the extent and frequency of costly repairs. Following the

Several factors in schools can contribute to poor IAQ. Some of the most common problems that contribute to poor IAQ include: Radon Classroom pets Excess moisture and mold Dry-erase markers and similar pens Dust and chalk Cleaning materials Personal care products Odors and volatile organic compounds

Combustion pollutants found indoors include: outdoor air, tobacco smoke, exhaust from car and lawn mower internal combustion engines, and some hobby activities such as welding, woodburning, and soldering. Combustion pollutants can also come from vented or unvented combustion appliances. These

The National Academy of Sciences (NAS) published its latest analysis of health research on radon, the Biological Effects of Ionizing Radiation (BEIR VI) Report in 1999 (see www.epa.gov/radon/health-risk-radon#beir). This is the most comprehensive review effort to date. The Committee was charged with

Levels in Homes Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher. Steps to Reduce Exposure to Carbon Monoxide It is most important to be

There is no debate about radon being a lung carcinogen in humans. All major national and international organizations that have examined the health risks of radon agree that it is a lung carcinogen. The scientific community continues to conduct research to refine our understanding of the precise

For further information on formaldehyde and consumer products, call the EPA Toxic Substance Control Act (TSCA) Assistance Line (202) 554-1404. Sources of formaldehyde in the home include building materials, smoking, household products, and the use of un-vented, fuel-burning appliances, like gas

Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing. Molds have the potential to cause health problems. Molds produce allergens (substances that can cause allergic reactions), irritants, and in some cases, potentially toxic substances (mycotoxins)
