What damage does radiation do?
Radiation exposure causes damage to the cells of your body, which can mutate them. Mutated cells are sometimes referred to as cancer cells, and thus radiation can give you cancer. There are different effects from different kinds of radiation, but mutating cells is the basic form of damage that radiation does.
Why radiation is dangerous?
Radiation, which comes in a couple of harmful forms, can be either electromagnetic or particulate. The dangerous electromagnetic radiation includes X-rays and the more potent gamma rays. Particulate radiation takes a number of forms which include alpha, beta, proton and neutron radiation. All these forms of radiation are what are called ionizing radiation. The ability of this radiation to penetrate varies, but the energies carried by ionizing radiation can damage genetic material within cells. This can result in cellular damage, mutation or even the death of the cell. Biologic material is seriously threatened by these types of radiation, and exposure should be minimized if not completely eliminated.
Which type of radiation can cause the most damage to the cells in the body?
The strongest type of radiation of course.
What are the dangers of neutron radiation?
Neutron radiation is as dangerous as any other ionizing radiation, if not more dangerous,as by some sources, it can be as many as ten times more dangerous as other ionizing radiation. It is not directly ionizing radiation, since neutrons do not hold electric charge, but they interact (collide) with nuclei in it's path, creating isotopes, most of the time non-sable, radioactive isotopes. That is why neutron radiation induces a secondary radiation in the material it passes through. The penetration of neutron flux is rather strong, and is not affected by the shield density, as is the case with gamma radiation, but rather by a material rich with Hydrogen (deuterium) atoms, since H atoms contain one single proton/neutron, and the collision physics slow down the neutrons in this matter most efficiently. Therefore, heavy water, plexiglass, plastics and similar materials are used as an effective shield in neutron radiation protection.
What are radioisotopes that emit alpha particles dangerous to soft tissues?
Alpha radiation that is external to the body is not harmful because the particles are absorbed by a few centimeters of air or by the thin layer of dead cells on the skin. However, if an alpha-radiating substance enters the body by ingestion, inhalation, or other means, some of the body's internal tissues receive a high dose of ionizing radiation, causing significant damage
Which of the following cell types are at least sensitive to ionizing radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
Which of the following cell types are least sensitive to ionizing radiation damage?
cells that divide slowly
Cell types are most sensitive to radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
How do you use the word ionizing in a sentence?
Some air cleaning systems work by ionizing and trapping dust particles. Ionizing radiation, such as gamma rays, can severely damage living cells.
How does the heating effect of absorbed radiation damage living cells?
well i was on here to find an answer but i found nothing, so they probably damage them by ionizing them causing cancerous cells or they can develop radiation sickness, this means the cells can have an abnormal cell, so when this divides it carrys on the chain.

Which cells of the body are most susceptible to radiation damage?
thyroid gland is one of the most sensitive organs..

What types of cells are most sensitive to radiation damage?
The ones with the shortest (normal) lifespans - like skin & the lining of the gut.
How can working with X-rays cause cancer?
Radiation is the emission (sending out) of energy from any source. The light that comes from the sun is a source of radiation, as is the heat that is constantly coming off our bodies. When talking about radiation, however, most people think of specific kinds of radiation such as that produced by radioactive materials or nuclear reactions. Most forms of radiation have not been linked to cancer. Only high frequency radiation (ionizing radiation and ultraviolet radiation) has been proven to cause genetic damage, which can lead to cancer. One type of molecule that is sensitive to ionizing radiation is DNA, the part of the cell that contains the genes (blueprints) for each person's characteristics. Ionizing radiation can lead to a mutation (change) in a cell's DNA, which could contribute to cancer, or to the death of the cell. All cells in the body can be damaged by ionizing radiation. The amount of damage is related to the dose of radiation received by the cell. While the process of cellular change from radiation takes only a fraction of a second, other changes such as the beginning of cancer may take years to develop.
Are cells that divide rapidly more sensitive to radiation?
No, they are just as sensitive as any other cell.
What harm can radiation can cause to living tissue?
When radiation strikes complex biological molecules such as proteins or nucleic acids ,it may fracture the molecules and prevent their proper functioning.This can result in loss of cell vitality,decreased enzyme activity, initiation of cancer and genetic mutations.
