What is the difference between radiation and radioactivity?
There is no difference in the meaning of the word. It is essentially the same thing. There are just two differenct forms of the word. You're still dealing with radium, Uranium, americium, and other radioactive elements either way.
What plant is used to detect radioactivity?
Certain types of spiderwort are used to detect radioactivity. Specifically the Ohio spiderwort, Tradscantia ohiensis can show low levels of radioactivity when the stamen hairs, which are normally blue, grow pink as a result of genetic mutation.
Do nuclear and atomic bombs are formed by nuclear radiation?
There are many types of nuclear radiation that have nothing to do with bombs, reactors, etc. In fact most radioactive material on earth was formed in supernovas billions of years before our solar system even formed. The materials used to make the active components of nuclear explosives are radioactive, however the designers of such explosives state that this radioactivity actually makes it harder to build reliable explosives. This radioactivity causes predetonation fizzles in fission bomb designs and aging/wear-out problems in all bomb designs. Another problem with radioactivity in nuclear weapons is the exposure hazard to personnel. For example the US Navy uses what is called Super Grade Plutonium, that has much less Plutonium-240 which is a strong gamma emitter than standard weapons Plutonium, in all their weapons that is very expensive to make. The principles used in nuclear explosives are nuclear fission and nuclear fusion.
Is radioactive energy the same as nuclear energy?
No. Dangerous radiation is produced by radioactivity, but equally dangerous radiation can also be produced by other means such as an X-ray machine. Radioactivity is the name we give to the processes where an unstable nucleus of an atom changes into a different nucleus. Particles such as alpha, beta and gamma are given off during the change; we refer to these particles as nuclear radiation. Radiation is technically any form of energy that can travel through space in the form of waves. So, light and microwaves and radio/TV broadcasting are all technically forms of radiation, and are not produced by radioactivity.
How is radiation used in your lives?
You use radiation in microwaves
What word is used to describe the particles and energy that are emitted by a nucleus?
radioactivity
What element is used to block out dangerous radiation?
Alpha Radiation ( α ) – Least penetration. Will be blocked by a single sheet of paper. Beta Radiation ( β ) – More penetration than alpha. Blocked by a few mms aluminium. Gamma Radiation ( µ ) – Strong penetration. Needs a least a few inches of lead to block.
What is a use of radioactivity materials in medicine?
Mainly twofold: kills dividing cells, used to visualize internal body.
How is radiation used to help the environment?
Radiation is used in removing toxic materials in the environment like some hazardous gasses in the air. Radiation is also used in some medical treatments.
What are the disadvantages of radioactivity to the world at large?
It can be dangerous. Thousands of people died from the radiation caused by the only 2 nuclear weapons used for war.

What materials are commonly used to shield living beings from potentially harmful radioactivity?
The protective apron used by dentists contains lead, which is highly opaque to radioactivity. (You would also notice that if you read Superman comic books; lead is used to safely contain kryptonite.)
A geiger counter measures radiation indirectly by measuring?
Levels of radioactivity are measured by a Geiger counter. Hans Geiger and Walter Muller created a practical radiation counter in 1928.
What is the device used to locate radioactivity?
A geiger counter is used to locate radioactivity in the environment.
For a solar collector to collect solar radiation what materials can be used?
Simple materials can be used like black plastic or metal pipe. You want materials that will absorb heat and transmit that heat to the liquid.
How different materials can be used to decrease radiation?
These materials are for impenetrable for gamma rays: lead, materials with lead (concrete, glass), materials containing boron or compounds, stainless steel etc.
What elememt is used for radiation shields?
Lead is usually used because of its density and ability to block electromagnetic radiation.
