Radiation exposure results in complex and persistent molecular and cellular responses that ultimately alter the levels of many biological markers, including the metabolomic phenotype. Metabolomics is an emerging field that promises the determination of radiation exposure by the qualitative and quantitative measurements of small molecules in a biological sample. This review highlights the current role of metabolomics in assessing radiation injury, as well as considerations for the diverse range of bioanalytical and sampling technologies that are being used to detect these changes.

  • Radiological Information
    RADIOLOGICAL INFORMATION Frequently Asked Questions Radiation Information A. Radiation Basics 1. What is radiation? Radiation is a form of energy. It is all around us. It is a type of energy in the form of particles or electromagnetic rays that are given off by atoms. The type of radiation we are concerned with, during radiation incidents, is “ionizing radiation”. Radiation is colorless, odorless, tasteless, and invisible. 2. What is radioactivity? It is the process of emission of radiation from a material. 3. What is ionizing radiation? It is a type of radiation that has enough energy to break chemical bonds (knocking out electrons). 4. What is non-ionizing radiation? Non-ionizing radiation is a type of radiation that has a long wavelength. Long wavelength radiations do not have enough energy to "ionize" materials (knock out electrons). Some types of non-ionizing radiation sources include radio waves, microwaves produced by cellular phones, microwaves from microwave ovens and radiation given off by television sets. 5. What types of ionizing radiation are there? Three different kinds of ionizing radiation are emitted from radioactive materials: alpha (helium nuclei); beta (usually electrons); x-rays; and gamma (high energy, short wave length light). • Alpha particles stop in a few inches of air, or a thin sheet of cloth or even paper. Alpha emitting materials pose serious health dangers primarily if they are inhaled. • Beta particles are easily stopped by aluminum foil or human skin. Unless Beta particles are ingested or inhaled they usually pose little danger to people. • Gamma photons/rays and x-rays are very penetrating.

  • Personal Preparedness Guide Radiological: Nuclear Explosion
    PERSONAL PREPAREDNESS GUIDE RADIOLOGICAL: NUCLEAR EXPLOSION What It Is: Nuclear explosions occur when two subcritical masses of highly processed radioactive material are thrust together suddenly, triggering a violent chain reaction and release of energy. Nuclear weapons are designed to cause catastrophic damage to people, buildings and the environment. Special highly guarded materials and expertise are required to construct and detonate a nuclear weapon. Damage from nuclear weapons fall into several categories. The explosion itself can demolish buildings and structures over a large area. The extent of the damage depends on the power of the bomb. Once the bomb explodes, it releases a fireball. This form of radiation can melt and burn some objects and skin, but clothing and opaque objects can provide some protection. However, the heat from thermal radiation is also the source of most of the post-blast fires. The intense heat of the fire causes an updraft, pulling oxygen in, making it difficult to breathe in the surrounding area. One of the unique effects of a nuclear blast is the electromagnetic pulse, which also emanates from the center of the blast. It disables all electrical devices in its path, rendering anything with a computer chip essentially dead. This poses an escape problem; newer cars with chips would not be able to start. Perhaps the most widely known effect of a nuclear attack is the fallout. When the bomb or missile explodes near the earth's surface, it pulls soil and water into a mushroom cloud, contaminating it with radiation. This matter settles back to the ground generally within a day and can be spread over a wider area by wind.

The purpose of this review is to present a concise overview of the types of radiation, methods of dispersal, injury patterns, and treatment considerations in a scenario involving radiation-based weapons of mass destruction. Radiation- related casualties, although uncommon, are a potential threat because more nations and organizations are developing the technology for producing radioactive substances capable of being used as weapons.
