There is some debate on that topic...
While there is no question that large acute exposure to ionizing radiation is dangerous and potentially lethal, the "jury is still out" on the question of long term exposure to low levels. The issue is that we don't yet have sufficient statistical proof one way or the other.
In fact, the average non-occupational dosage in the US is approximately 200 millirem per year, half from medical sources, and half from natural sources.
Some people even think that some long term exposure is necessary, as part of the driving forces that keep us healthy by forcing our cells to repair themselves.
Since the question remains open, and a hot (:-)>) topic, the nuclear industry has adopted the principle of ALARA, which means As Low As Reasonably Achiveable, so we essentially minimize dosage, both to radiation workers, and to the general public.
Keep in mind that the medical community semi-routinely doses us, such as in a nuclear stress test, with several REM, while the radiation worker community would be horrified if that happened to someone in a short period of time.
Its all a matter of degree, and the body's ability to repair itself.
Yes, ionizing radiation is classified as high energy photons capable of damaging chemical bonds, i.e. human cells and tissue. Exposure to ionizing radiation leads to what is known as radiation sickness, which in effect is the result of excessive damage to cells and the DNA contained within
It can make our environment destroyed and the human living things died...
radiation can cause living things to mutate.
Harm or damage them
The alpha particles have an ionising effect changing the polarity of parts of the cells in your body. this then causes your genetic information to become mixed up, causing mutation or death of the cells, the first causing cancerous growths, the latter causing burns.
Because it breaks chemical bonds in the cells. Good luck on UTexas! :)

ionising radiation can break molecules into ions. these ions take part in other chemical reactions in the body cells. for example these ionization can break the bonds in the DNA bases and cause mutations. or can interrupt with the processes like respiration that provides cell with energy. ionisation can also produce radicals that take part in other chemical reactions in the body like electric impulses from the brain and can damage the nervous system. hope that helps !)
The chloroplasts have clumped into the middle. This demonstrates the effect on a hypertonic solution on living cells. :)
Body cells are made of atoms and if ionising radiation occurs, your cells would lose electrons and this could cause mutations etc
It is a type of ionising electromagnetic radiation. Ionising radiation is radiation composed of particles that individually have sufficient energy (or can liberate sufficient energy) to remove an electron from an atom or molecule, i.e., in this situation humans. It damages the cells of your skin essentially by smashiing into it.

When ionising radiation interacts with living cells is usually kills these cells. Thus yes, radiation can kill pancreatic cells that are cancerous. However the radiation will also destroy healthy cells (and destroy the pancreas) so the amount of radiation given has to be low and well targeted. This is difficult to achieve and if any cancerous cells remain alive they will regrow the cancer.
This is not a routine practice, but it is desirable when transfusing animmunocompromised patient, as the T-lymphocytes in the transfused blood may otherwise provoke a graft-versus-host reaction. Low-dose ionising radiation inactivates the T-lymphocytes without harming the other blood components. Radiation has also been proposed as a method of sterilising the blood units, but much higher doses, which are not necessarily well tolerated by the blood cells, are needed for this purpose.
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.

When a living body absorbs radiation, the radiation can cause shemical changes in the body. Some of these Might effect the DNA and cause a rapid, out of control growth of cells...CANCER.
UV light is a type of radiation that generally has negative consequences on living cells.

A beta particle is equivalent to an electron. The difference is that beta particles originate in the nucleus before they are ejected while electrons originate outside the nucleus.
