This result demonstrated an evidence for indirect action of ionizing radiation on individual components of the complexes and was reasonably described by a positive "hole" transfer from primary macrocyclic radical cation to fluorous anion at the primary stages of radiolysis and a subsequent interaction of fluorine atom with 18C6 macrocycle in secondary radical reactions.

When cells are exposed to ionizing radiation, radiochemical damage can occur either by direct action or indirect action. Direct action occurs when alpha particles, beta particles or x-rays create ions which physically break one or both of the sugar phosphate backbones or break the base pairs of the DNA.

Indirect effects. Indirect effects are caused by interaction of radiation usually with water molecules. Each cell, just as is the case for the human body, is mostly water. Ionizing radiation may break the bonds that hold the water molecule together, producing radicals such as hydroxyl OH, superoxide anion O 2 – and others. These radicals can contribute to the destruction of the cell.

08.05.2020 · Indirect ionizing radiation is electrically neutral and therefore does not interact strongly with matter. The bulk of the ionization effects are due to secondary ionizations. An example of indirectly ionizing radiation is neutron radiation.

These are radiations that carry no electrical charge and produce ionization by first setting free a charged particle, which itself may then ...

18.01.2020 · Directly ionizing radiation consists of charged particles. Such particles include energetic electrons (sometimes called negatrons), positrons, protons, alpha particles, charged mesons, muons and heavy ions (ionized atoms). Indirectly ionizing radiation consists of uncharged particles. What is somatic effect?

Cellular macromolecules are modified by direct ionization and via the reactivity of the high-energy species originating from water radiolysis (indirect effects ...

If the absorption of radiation occurs in the molecule in which the lesion appears, then this is the direct action of radiation,while with indirect action ...

27.01.1987 · radiation must produce ionization within a few nanometers of the DNA molecule in order for this action to occur. B. Indirect Action In the second scenario, the radiation interacts with non-critical target atoms or molecules, usually water. This results in the production of free radicals, which are

Direct ionization occurs when charged particles, e.g., electrons, with sufficient kinetic energy interact with cellular atoms or molecules to create free ...

If the absorption of radiation occurs in the molecule in which the lesion appears, then this is the direct action of radiation ,while with indirect action the absorption of the radiation energy and the response to this energy occur in different molecules.
