Answer 1

Answer:

Let us go to the basics first.

The X-Rays can be easily stopped by a solid body. (False) (Answer)

Example: X-Rays very easily pass solid bodies like human body, etc.

The leading source of naturally occurring radiation is: Uranium (Answer).

If a radioactive atom emits alpha rays, a transmutation of the associated element occurs. (True) (Answer).

Reason: If a radioactive atom emits alpha rays, changing of an atom into another kind of atom that takes place.

In the atomic nucleus we find protons and neutrons bound together by electromagnetic forces. (False) (Answer)

Reason: In the atomic nucleus, protons and neutrons are bound together by strong Nuclear force.

Radiation dosage is usually measured in RADS.1 RAD = 0.01 J/kg. (Answer) ==> None of the above

Beta and Alpha rays may be deflected by applied magnetic fields. (True) (Answer)

Reason: Alpha particles are positively charged, beta particles are negatively charged. This means that alpha and beta radiation can be deflected by magnetic fields.

Beta rays are emitted by a radioactive nucleus when one of its neutrons becomes a proton after emitting an electron. (True) (Answer)

The X-Rays were initially discovered in: Cathode rays (Answer).

Gamma Rays involve a positive electric charge. (False) (Answer)

Reason: Gamma rays are neutral.
