   What is ionizing radiation?

   • Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts (eV), which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms.

   What are the two types of radiation?

   • In short, the two broad classes of radiation are unambiguously differentiated by their speed of propagation and corresponding presence or absence of rest mass. In the discussion that follows, those of the first category are referred to as “electromagnetic rays” (plus the neutrino) and those of the second as “matter rays.”

   What is a radiation source?

   • 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. Human-made radiation sources are widely used in medicine, industry, and research.

   放射性的標誌。Unicode所收錄的編碼為U+2622（ ） 放射性或輻射性 [1] 是指某核種的原子核不穩定，會自發性地放出游離輻射（如α射線、β射線、γ射線等）而衰變成另一種核種（衰變產物），這種特性稱為放射性。 衡量放射性強度的國際單位為貝克勒（Bq），傳統單位則為居禮（Ci）。
