Remember, radioactive fallout on a surface does not make the surface itself radioactive. The particles themselves are radioactive, not the surface they come in contact with. The surface can usually be cleaned of any contamination
False
The energy that comes from the radioactive decay of an atom can come from the electrons and can come from the strong force inside the nucleus.
This is chiefly due to the fact that the earth's core is incredibly hot--perhaps hotter than the surface of the sun (most of the heat in the core comes from the radioactive decay of elements). Friction from convection in the mantle also adds heat, and near the surface (within the crust) pressure has an effect on increasing temperature at depth.
when sodium comes in contact with water,it results in an exothermic reaction to give sodium hydroxide.
Radiolabel the sugar oxygens, then carry out the reaction and see if the carbon dioxide that's released is radioactive or not. Alternatively, you could use radioactive oxygen gas.
What procedure to follow if exposed skin comes in contact with any chemical substance
Being very radioactive protactinium is dangerous.
Surface that touch food are called "food contact surfaces".
When nuclear fallout comes usually everyone shoots people in the head with their magnums
it comes in contact with air
Nuclear Fallout comes from a nuclear power plant.
The surface of the mirror is cooler than the surroundings. When the water vapour comes into contact with the surface of the mirror, they condense.
there is a Fallout New Vegas so watch out for it. it sucks because it comes out next year in 2010
to avoid salmonella-based foodpoisoning.
The heat that drives mantle convection comes from the colling of Earth's interior and the decay of radioactive isotopes
True. Friction is the force that resists motion when the surface of one object comes in contact with the surface of another
The footsteps last permanently on the surface of the moon until an object comes in contact with them. In case you were curious, the reason why the footsteps will last so long is because the moon does not have an atmosphere interacting with the surface.
As soon as the Cement comes into contact with water. This will start as soon as the cement and aggregates come into contact unless the aggregates have been dried of all surface water.
