There are four types of radiation, designated in the Greek alphabet. (firechief.com)

Among them is nuclear energy , which is touted to be the most potent energy source due to its high latent power, and that's because of its high level of radiation. (conserve-energy-future.com)
This is only a hazard for those on the plant site, and the level diminishes with distance from the radioactive source. (world-nuclear.org)
This is important where radiation measurements are taken of a specified radiation source, where the existing background may affect this measurement. (wikipedia.org)
A radiation detector records a low reading even when no radioactive source is close. (askfilo.com)
The chemical, metal, gas, radiation, or other environmental toxin can travel from the source to you in the air, water, or soil or in food or beverages you consume. (cdc.gov)
