Learn the Issues

This page shows all of the pages at www.epa.gov that are tagged with Learn the Issues.

  • Radiation Sources and Doses

    Radiation dose and source information the U.S., including doses from common radiation sources.

  • Food Irradiation

    Food irradiation can help prevent foodborne illness, also known as food poisoning. Food irradiation does not make food radioactive.

  • Radiation Protection Science and Tools

    Landing page for Radiation Protection Science & Tools including TENORM, Basics, and tools for calculating dose and risk

  • Radiation Protection Regulations, Guidance and Compliance

    EPA standards set protective limits on the radioactivity in soil, water and air that comes from human use of radioactive elements. EPA issues federal guidance documents with recommendations on radiation protection.

  • Protecting Yourself from Radiation

    The concepts of time, distance and shielding will help protect you from radiation. In the case of a radiation emergency, get inside, stay inside and stay tuned.

  • Radiation Terms and Units

    Different aspects of radiation have their own terms and units and are presented here.

  • Radiation Health Effects

    View basic information about how radiation affects human health, including the concepts of acute and chronic exposure, internal and external sources of exposure and sensitive populations.

  • Radioactive Decay

    Radioactive decay is the emission of energy in the form of ionizing radiation. Example decay chains illustrate how radioactive atoms can go through many transformations as they become stable and no longer radioactive.

  • Radionuclides

    Information about radionuclides and links to additional information about specific radionuclides.

  • Protective Action Guides (PAGs)

    The Protective Action Guide (PAG) manual contains radiation dose guidelines that would trigger public safety measures. EPA developed Protective Action Guides to help responders plan for radiation emergencies.

  • Oil Spills Research Recent Publications

    Recent journal articles and EPA reports.

  • Non-Ionizing Radiation Used in Microwave Ovens

    Microwave ovens use electromagnetic radiation to heat food. The non-ionizing radiation used by a microwave does not make the food radioactive.

  • Nuclear Gauges

    Nuclear gauges measure three main things: thickness, density, and fill level. When properly used, nuclear gauges will not expose the public to radiation.

  • Radioactive Material in Science Classrooms

    Chemistry, physics, and earth science labs are some of the places where radioactive materials could be used in schools. Talk to your science teacher to find out how you can learn more about experiments using radiation in your school.

  • Frequent Questions: Radiation Sources

    View frequently asked questions and answers related to radiation sources by topic.

  • Electric and Magnetic Fields from Power Lines

    Electromagnetic fields associated with electricity are a type of low frequency, non-ionizing radiation, and they can come from both natural and man-made sources.

  • Mail Irradiation

    During the irradiation process, mail must pass through a high energy beam of ionizing radiation in order to kill harmful bacteria. Irradiation does not make the mail radioactive.

  • Ultraviolet (UV) Radiation and Sun Exposure

    While we need some exposure to sunlight to help our bodies make vitamin D, too much UV is dangerous. Almost half the daytime total of UV radiation is received between 10 a.m. and 4 p.m. Even on a cloudy day, you can be sunburned by UV radiation.

  • Radioactive Fallout From Nuclear Weapons Testing

    After a nuclear explosion, debris and soil can mix with radionuclides. This mixture is sent up into the air and then falls back to Earth. It is called fallout and it typically contains hundreds of different radionuclides.

  • Frequent Questions: RadNet Near-Real-Time Air Monitoring

    View frequently asked questions about the RadNet near-real-time air monitoring.
