United States Department of Health and Human Services, Radiation Emergency Medical Management
A route by which a radionuclide or other toxic material can enter the body. The main exposure routes are inhalation, ingestion, absorption through the skin, and entry through a cut or wound in the skin.
Industry:Medical devices
A measure of the ionization produced in air by x-rays or gamma rays per unit of time (frequently expressed in roentgens per hour).
Industry:Medical devices
External irradiation occurs when all or part of the body is exposed to penetrating radiation from an external source. During exposure, this radiation can be absorbed by the body or it can pass completely through. A similar thing occurs during an ordinary chest x-ray. Following external exposure, an individual is not radioactive and can be treated like any other patient. Gamma or photon radiation exposure from a terrorist nuclear event or radiation dispersal device would make the victim at risk for acute radiation syndrome, depending on the dose received.

Industry:Medical devices
Minute particles of radioactive debris that descend slowly from the atmosphere after a nuclear explosion. For more information, see chapter 2 of cdc’s fallout report (pdf - 32.24 mb).
Industry:Medical devices
Healthcare workers in a hospital or other facility where victims arrive for treatment. First receivers provide medical care at locations remote from the incident and not at the site of a hazardous materials release. Since victims may arrive for treatment still contaminated with hazardous materials, first receivers must also protect themselves by putting on appropriate ppe before delivering medical care.
Industry:Medical devices
An individual responsible for protecting and preserving life, property, evidence, or the environment during the earliest stages of a mass casualty event or other emergency. First responders generally work at or near the incident site.
Industry:Medical devices
Any material in which neutrons can cause a fission reaction. The three primary fissile materials are uranium-233, uranium-235, and plutonium-239.
Industry:Medical devices
The splitting of a nucleus into at least two other nuclei that releases a large amount of energy. Two or three neutrons are usually released during this transformation. See also fusion.
Industry:Medical devices
A cytogenetic technique used to detect and localize the presence or absence of specific dna sequences on chromosomes.
