What is ionizing radiation and how can we reduce the risk of it damaging us?
Ionizing radiation is electromagnetic radiation or particulate radiation having enough energy per quantum to remove electrons from atoms, thus creating positive ions.The types of electromagnetic radiation with enough energy per photon (the quantum of electromagnetism) to ionize atoms are:ultraviolet Cx-raysgamma raysThe types of particulate radiation with enough energy per particle (i.e. quantum) to ionize atoms are:alpha particlesbeta particlescosmic rays (both primary and secondary)The only way to reduce the risk is to minimize exposure, but remember exposure cannot be completely eliminated as all of these types of ionizing radiation are present at low dose rates all around us.
What are the best ways to protect against the effects of exposure to radiation?
Ionizing radiation is "stopped" by passing the radiation through matter which becomes ionized. By definition, ionizing radiation will ionize material that it passes through. Ionization involves transferring energy, so the entity doing the ionizing loses energy. That is the simple answer. A closer look reveals greater complexity. One needs to be clear about language to be accurate in the question and answer. Normally when referring to ionizing radiation, one is referring to high energy particles that are causing the radiation. Normally, when we say such radiation is "stopped" we mean it is diminished to that the harmful effects are insignificant. One does not "stop" such radiation but rather one causes it to lose energy. There will always be a few stray particles with high energy even after the vast majority have lost so much energy that ionization has stopped occurring. If one wants to "stop" ionizing radiation, then creating a large enough (thick enough) barrier will effectively reduce the radiation to insignificance. Of course, depending on the nature of the radiation, some materials may be more effective than others in removing the energy from the radiation. Though ionization, i.e. exicting or removing electrons of atoms, is an important energy loss process, there are also processes that involve the interaction of the ionizing radiation with the nuclei of the material through which it passes. Bremsstrahlung is one such process and so is simple transfer of kinetic energy from the incident particle to the particle in the material. These kinds of processes are larger or smaller depending on the mass and energy of the "ionizing radiation" and so an effective discussion of how well a material can "stop" ionizing radiation depends on the ionizing radiation itself.
How do you protect ourselves from gamma rays?

Why can we compare the ozone layer to sunscreen?
They both reduce your exposure to ultraviolet radiation.
What can you do to reduce exposure to nuclear radiation?
Wear a badge containing photographic film.
The rate at which a rock in a streambed dissolves would not be increased by .?
Reduce the rocks exposure
How can you reduce exposure to radiation to mimimize the risk of health effects?

How do you stop being damaged by exposure to x-rays?
The way to stop being damaged by exposure to x-rays is to reduce or eliminate your exposure to x-rays from man-made sources. There is little you can do about naturally occurring x-rays.
What are nursing actions to reduce exposure to pathogens for a client who is immunocompromised?
Avoid too many visitors especially children
How does diversification affect financial institions credit risk exposure?
Generally, diversification helps reduce the overall credit risk exposure for financial institutions by reducing their overall expected chargeoff rates.
