Answer:

Paper will not stop any radiation.

Copper will stop beta radiation.

Lead will damp the gamma radiation

Explanation:

A Geiger counter is an instrument used to measure the radiation level. There are majorly three types of radiation: Alpha, beta and gamma. Alpha radiations have least energy and gamma radiation have the highest energy. Alpha radiation can be stopped even by a sheet of paper. Beta radiation can be stopped using a sheet of aluminum or copper. To stop the gamma radiation you need lead. Also, the energy of the gamma radiation and thickness of the lead shield will decide how much of the gamma radiation is stopped by the lead sheet.

In the given scenario, when only paper is used neither beta nor gamma radiation will be stopped and Geiger counter will show you the high radiation level. When the source is lined with copper and lead, beta radiation will be stopped and gamma radiation will be damped. So Geiger counter will show reduced level of radiation.

How long does a player sit out of a game of handball for committing a second or third foul?
yulyashka [42]

Answer:

Walking’ - If a handball player takes more than three steps without dribbling (bouncing the ball) or holds the ball for more than 3 seconds without bouncing it, shooting or passing, then that is deemed ‘walking' and possession is lost.

'Double dribble’ - Handball players cannot receive the ball and bounce it, then hold the ball, and bounce it again. This is termed ‘double dribble’ and is against the rules.

Explanation:

  • Drain certain surfaces throughout warm water of such soap during the very first sink. This same sanitizing of bacteria would not destroy whether grime would be in the direction.
  • Exfoliate the plates throughout plain water during the secondary drain. As with grime, the residual soap could avoid the kill off bacteria and viruses by the sanitizer.
