Does phone really have radiation that is harmful to humans?
Cell phones do emit a type of non-ionizing radiation.
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.
What cell types are most sensitive to radiation damage?
The ones with the shortest (normal) lifespans - like skin & the lining of the gut.
When is radiant energy harmful?
The danger of radiation, specially ionizing radiation, is the capacity to harm the genetic material. Ionizing radiation can break double the strand of DNA and inactivate vital genes necessary for living or health of the organism. Depending upon the intensity of the radiation, the cell can undergo death (e.g., apoptosis or programmed cell death) or to carry a genetic defect that is inherited to the next generation.
What is meant by the term background radiation?
Backround radiation is an explosion which occured in space, which consists of radiation comming from all directions in space.
Which of the following cell types are least sensitive to ionizing radiation damage?
cells that divide slowly
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.
Cell types are most sensitive to radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
What are some examples of non ionizing radiation?
mobile/cell phones microwaves radiation and power lines
Does phone really have radiation that is harmful to humans?

When ionizing radiation interacts with the suspending medium of the cell?
Indirect-hit interaction
How radiation effect normal cell?
Ionizing radiation has the ability to harm proteins and change the sequence of DNA, causing mutations. This can have harmful effects for the cell
The initial effect of ionizing radiation on a cell is that it causes?
The formation of highly reactive ions
Are cells that divide rapidly more sensitive to radiation?
No, they are just as sensitive as any other cell.
What is nonionizing radiation?
Ionizing radiation causes some of the atoms it strikes to be ionized. There are several different types: alpha particles, beta particles, neutrons, gamma rays, x-rays, and ultraviolet light. Non-ionizing radiation, which does not ionize atoms, includes visible light, infrared light, radio waves, and so on.To understand the biological effects of radiation we must first understand the difference between ionizing radiation and non-ionizing radiation. In general, two things can happen when radiation is absorbed by matter: excitation or ionization.Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.Because living tissue is 70-90% water by weight, the dividing line between radiation that excites electrons and radiation that forms ions is often assumed to be equal to the ionization of water: 1216 kJ/mol. Radiation that carries less energy can only excite the water molecule. It is therefore called non-ionizing radiation. Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation.Related links are provided below.
