What is direct effect of radiation?
If radiation interacts with the atoms of the DNA molecule, or some other cellular component critical to the survival of the cell, it is referred to as a direct effect. Such an interaction may affect the ability of the cell to reproduce and, thus, survive.
What is direct and indirect radiation?
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.
What are the two effects of radiation?
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.
What is an indirect hit in radiology?
Direct hit and Indirect hit. direct hit. It is the breakage of the DNA molecule as a result of being struck by an x-ray photon. indirect hit. It causes a chemical reaction in the water causing a formation of free radicals which may interact with the DNA or may combine to produce toxic substances that damage the DNA.
What is meant by an indirect effect of ionizing radiation?
Cell damage can be caused by direct or indirect ionization. Indirect ionization occurs when non-charged particles, e.g., photons, interact with cellular water. In turn, these free radicals interact with cellular atoms and molecules damaging cellular proteins and may form additional free radicals.
What is the difference between direct and indirect action?
Direct or indirect refers to the relation between an action and its effect on the environment. In that sense, direct actions are characterised by the relation between people and the environment, while indirect actions are characterised by the relation between people.
What is radiation and its effects?
Radiation can damage the DNA in our cells. High doses of radiation can cause Acute Radiation Syndrome (ARS) or Cutaneous Radiation Injuries (CRI). High doses of radiation could also lead to cancer later in life.
What is the effect of radiation in environment?
Plants and animals within the affected area take up radioactive particles, and these move through the ecosystem through bioaccumulation. Radiation pollution within waterways also accumulates within fish and other aquatic organisms, and runoff from radiation within the soil provides additional contamination.
What are the somatic effects of radiation?
Somatic effects are those suffered by the exposed person. Hereditary effects are those suffered by the offspring of the individual exposed. Cancer risk is usually mentioned as the main stochastic effect of ionizing radiation, but also hereditary disorders are stochastic effects.
