0 a method of protecting yourself from a disease that involves staying at home and having as little contact as possible with people from outside your home, because you are at risk of becoming seriously ill if you get the disease:
1 sheets of metal, plastic, etc. used to protect workers or other people from harmful materials, diseases, radiation, etc.:
2 the practice of keeping your body between an opponent and the ball, with your back to the other player, to prevent them from getting the ball:
The addition of conformal shielding without changes to beam orientation produces a further small dose reduction to all the normal tissues investigated.
This is due to the difference in the shielding of the target nuclei between the two cases.
The shielding is thus less effective in the completely ionized plasma and the angular dispersion of the scattered beam larger.
In addition, a faster overall cycle time can be achieved which reduces the costs of consumables such as shielding gas.
Especially large numbers of error was detected in the process from treatment errors occurring with the shielding blocks drew preparation to treatment delivery.
Behind does a shielding operation by using the pictures in the second sequence to mask out overlapping portions of the pictures in the first sequence.
The shielding level was about 10-6 of the terrestrial magnetic field.
For background reduction, a careful shielding of the image intensifier against neutrons is required.
