CHICAGO, April 19 (Reuters) - Drugs commonly used to strengthen bones to prevent osteoporosis may protect people exposed to radiation against developing leukemia, U.S. researchers said on Sunday. Sign ...
Doctors are reporting improved survival in men with advanced prostate cancer from an experimental drug that delivers radiation directly to tumor cells. Few such drugs are approved now, but the ...
Radiation is energy that travels in the form of waves or particles and is part of our everyday environment. People are exposed to radiation from cosmic rays, as well as to radioactive materials found in the soil, water, food, air and also inside the body.
Radiation is the emission of energy as electromagnetic waves or moving subatomic particles. Natural radiation comes from many naturally occurring radioactive materials found in soil, water, air and in the body. Every day, people inhale and ingest forms of radiation from air, food and water.
Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized. Here we are concerned with only one type of radiation, ionizing radiation, which occurs in two forms: waves or particles. There are several forms of electromagnetic radiation, which differ only in frequency and wavelength: Longer ...
We work to strengthen radiation protection of the public, patients and workers worldwide. We provide Member States with evidence-based guidance, tools and technical advice on public health issues related to ionizing and non-ionizing radiation.
