What are three primary techniques for minimizing exposure to radiation and radioactive materials?

One is to stay away from it. Proximity is important.
Another is to keep the exposure time as short as possible.
A third way is to use an effective shield. This is very important. The actual nature of the shield is also very important, and depends on the nature of the radiation involved.
Alpha particles can be shielded with almost anything, as long as they are not ingested or inhaled - they can be stopped by a piece of paper. Beta particles and gamma particles require a bit more, but can be shielded by materials with high atomic numbers, such as lead. Neutrons are not well shielded by lead, but are well shielded by water.

What is radioactive substances?
Radioactive substances are the things that put off radiation. These could be radioactive waste, or even radioactive materials not yet used.
Does radiation need particals?
No, some radioactive materials are not solids. Most radioactive materials are solids (uranium, plutonium, isotopes of many other materials) Some radioactive materials are gases (Radon) or isotopes of gases (Tritium, carbon fourteen, etc.)
What changes in a radioactive material to make it emit radiation?
Due to unstable atomic structures (or a weak nuclear force), radioactive materials release alpha particles as radiation.
Is there a such thing as radiology?
Yes. It is the diagnosis and/or treatment of disease using radiation or radioactive materials.
Why the radioactive material must be placed in a box of lead?
Radioactive materials emit dangerous radiation; most of this will be blocked by a box of lead.
What is the danger of nuclear radiation?
Ionising radiation from Alpha, Beta and Gamma emissions (from radioactive materials) are harmful to most organs of the body.
Why only radioactive element give out radiation?
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Most of the high-level hazardous radiation associated with nuclear energy is the result of?
Waste materials, mining and transportation of radioactive fuels, radiation emissions from nuclear sites.
Is food and drink a natural source of radiation?
Most background radiation comes from natural sources, while most artificial radiation, plants absorb radioactive materials from the soil and these pass up the food chain.
What type of device causes purposeful dissemination of radioactive materials across an area without nuclear detonation?
radiation dispersal device
Why do rocks and soil emit small amounts of radiation?
Radioactive materials(uranium, thorium and radium) exist naturally in soil and rock.
What is radiation exposure safety?
Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
