10 Facts About Radiation shielding

The effectiveness of shielding is dependent on stopping power, which varies with the type and energy of radiation and the shielding material used.

Different shielding techniques are therefore used depending on the application and the type and energy of the radiation.

Graded-Z shielding is a laminate of several materials with different Z values designed to protect against ionizing radiation.

Lead shielding wear such as lead aprons can protect patients and clinicians from the potentially harmful radiation effects of day-to-day medical examinations.

Recent studies show that copper shielding is far more effective than lead and is likely to replace it as the standard material for radiation shielding.

One technique is to apply selective Radiation shielding to protect the high concentration of bone marrow stored in the hips and other radio-sensitive organs in the abdominal area.

Radiation shielding emitted by the Sun and other galactic sources, and trapped in radiation "belts" is more dangerous and hundreds of times more intense than radiation sources such as medical X-rays or normal cosmic radiation usually experienced on Earth.

NASA Space Radiation shielding Laboratory makes use of a particle accelerator that produces beams of protons or heavy ions.

Radiation shielding stressed that "animals vary in susceptibility to the external action of X-light" and warned that these differences be considered when patients were treated by means of x-rays.
