A radiation shield should have high reflective power.
Radiation shields are used to protect people, equipment, and the environment from the harmful effects of radiation. They are designed to block or reduce the amount of radiation that passes through them. There are different types of radiation, including ionizing radiation (such as gamma rays and X-rays) and non-ionizing radiation (such as infrared and radio waves). The choice of radiation shield material depends on the type and energy of the radiation to be blocked.
Importance of reflective power
One of the important properties of a radiation shield is its reflective power. Reflective power refers to the ability of a material to reflect or bounce off radiation rather than absorbing it. This is crucial because if a material absorbs radiation, it may heat up and transfer that heat to the surrounding environment, potentially causing damage or harm.
High reflective power
A radiation shield with high reflective power is desirable because it can effectively reflect the incident radiation away from the protected area. This prevents the radiation from reaching the target and reduces the risk of exposure or damage. By bouncing off the radiation, the shield can redirect it away from sensitive areas, thus providing a higher level of protection.
Alternatives
The other options mentioned in the question are not suitable for a radiation shield:
a) High transmissivity: This means that the shield allows radiation to pass through it, which is not desirable for protection purposes.
b) Absorbing all radiations: This would result in the shield absorbing the radiation, potentially leading to heat buildup and transfer to the surrounding environment.
d) Partly absorbing and partly transmitting radiation: This option may provide some level of protection by absorbing a portion of the radiation, but it does not offer the same level of effectiveness as a shield with high reflective power.
In summary, a radiation shield should have high reflective power to effectively reflect the incident radiation away from the protected area, reducing the risk of exposure or damage.
