Hi
I am doing shielding at power frequency using femlab. i have done 2D modeling on a room using reinforcement bars instead of a full shield and i wonder why is the bar inclined at 45 degrees will give a better shielding effeciency than at 90 degree?
in the real world, when do we use...
Hello, i have to do a problem for a written problem set:
1. Shielding. The transport of radioactive samples must follow strict guidelines to ensure that the exposure is very low. A 100 mCi sample of 212Pb is placed at the centre of a cubical lead lined box, each side of which has a length of...
space stations are to be protected from
1. galactic cosmic rays
2. solar flares
3. other harmful solar radiation
for protechtion we Can use
1. lunar soil
2. electtromagnetic shield Etc...
BUT IS THERE A WAY TO HAVE TRANSPERENT SHIELD
SO THAT LIGHT CAN ENTER ?
CAN...
1. how does NASA protect its robots in space(eg satellites, space stations etc) from solar radiation ?
( their processors, chips etc )
I've checked lot of sites for it but none of them mentioned about their shielding. does this mean that radiation have negligible effects on robots??
2...
Is there a substance that can be placed between two magnets that will stop one from affecting the other? If a sheet of paper is placed between the magnets it has no affect. This is obvious but what i want is a substance that can be placed between two magnets that are placed very close together...
Now this relates to the berylium + Lithium thread i made earlier.. (although not entierly)
Is electron 'shielding' due to replusion between electron orbitals?
