There are two models, essentially, that radiobiologists use to explain this phenomena of ionizing radiation damage to cells. One is direct target theory, which explains both chromosome damage and cell death, the other is indirect action, which is associated more with cell death. Direct target theory assumes that the ionizing radiation interacts with the cellular macromolecule, such as DNA or RNA, breaking the electron bonds (hence, ionizing), and causing disruption or change in the biologic function of that molecule. Sometimes this damage can be repaired, sometimes the damage is fatal to the cell. If the ionizing occurs in the DNA molecule, which is the structural component of the chromosome, the damage may change the chromosomal function, and if the cell lives, may be passed on to the offspring as genetic mutation. Please note however that any observed mutations are the same mutations one would see in the population naturally. Unlike the movies, radiation induced mutations aren't determined by the type of mutation, but determined by the occurance of exposure to radiation. Indirect action occurs when the water in the cell is ionized, creating free radicals, which further create hydrogen peroxide and oxygen in the cell. This chemical molecule in the cell typically kills the cell. Of the two methods of interaction, the indirect method is thought to occur most often. Gregory G. Passmore, Ph.D., CNMT
Mutagens are agents that can induce changes in chromosomes, usually by causing DNA damage or mutations. These changes can lead to alterations in the genetic material carried by the chromosomes, impacting the traits and functions of an organism. Examples of mutagens include ionizing radiation, certain chemicals, and some viruses.
It's mutations.
Within a certain dosage range it can, especially in the intestines and some sensitive organs.
None. By radiation, we're referring to ionizing radiation, or radiation with high enough energy to cause molecular damage, or possibly DNA damage. Radiation therapy, CT scan, Nuclear scans and X-rays all use ionizing radiation. MRI uses magnetic fields to induce electric currents, and employs radiofrequeny waves ( a type of electromagnetic radiation) that is not ionizing radiation. It is a form of energy, and thus metal objects, and even metal in tattoos can heat up and cause burns.
Radiation current is the flow of electric current due to electromagnetic radiation interacting with a material. When radiation, such as light or radio waves, strikes a material, it can induce the movement of charged particles within the material, resulting in a current flow. Radiation current is important in areas such as solar cells and detectors for measuring radiation levels.
quality assurance is a maintain and control the quality of radiation treatement machine.we are treating the patien with radiation.if execes of dose receive it can induce secondary malignancee.so we have to qa dosimetry for radiation treatement.
Exposure to ultraviolet (UV) radiation can cause DNA damage and lead to a base sequence change. UV radiation can induce thymine dimers, where two adjacent thymine bases bond together, leading to errors during DNA replication.
No. There is no way it could possibly induce movement in a coin; to begin with, the signal is extremely weak.
Visible light does not cause transmutations as it does not have enough energy to induce changes in atomic nuclei.
In a tanning bed, electrical energy is transformed into thermal energy and UV radiation. The thermal energy heats up the bulbs to produce UV radiation, which then interacts with the skin to induce tanning.
They can induce current which can damage internal computer components.
Vomiting causes other serious problems, including acid-related scarring of the fingers (if used to induce vomiting) and damage to tooth enamel.
