slide 2: Traditionally radiation shielding materials have for the most part been manufactured using
lead. From industrial and nuclear shielding to radiation therapy lead found its way into most
spheres of shielding simply because its attenuating qualities made it the ‘m a te ri al of c h o i c e ’
when it came to radiation protection. However lead poses all kinds of health risks and
severe cases of lead poisoning have also resulted in death. It seems particularly
counterintuitive to introduce the use of lead a known toxic material in use at hospitals and
for medical treatment where one goes to receive health benefits and not to be exposed to
further health risks. Given our increasing sensitivity towards the dangers of leadthere is a
growing demand for lead free shielding materials and we have several options to choose
from when it comes to choosing radiation shielding equipment.
slide 3: Lead Shielding
Lead atomic number 82 symbol Pb is a malleable soft and corrosion-resistant metal that
comes with a high density and is incredibly useful in terms of x-ray shielding and gamma-ray
shielding. In order to transform lead into a shielding material it is mixed with additives and
binders. This converts lead into a flexible vinyl sheet which is layered to achieve the desired
thickness and incorporated into different types of radiation shielding equipment. The most
common levels of lead protection include 0.25mm 0.35mm and 0.
slide 4: Lead Composites
Lead composites or lead composite shielding refers to a mixture of lightweight metals and
lead. This proprietary mixture varies from one manufacturer to the other but you can
always expect non-toxic high density materials such as tin PVC vinyl and rubber to find
their way into the blend. The biggest advantage of using a lead composite is that it is up to
25 lighter when compared to regular lead shielding materials despite offering the same
protection against radiation. However they still pose the same health risks as lead.
slide 5: Lead Free Shielding
The third and most important type is lead-free shielding which is produced from a blend of
composite materials that eliminate the need for lead entirely without compromising on
radiation protection. Leadfree shielding materials are created by mixing heavy metals such
as bismuth antimony tin and tungsten metals with polymers. The biggest advantage that
these materials have to offer is that they are entirely recyclable and unlike lead or lead
composites they d o n ’ t pose any health hazards.
slide 6: Choosing Between the Three
Each of these core shielding materials has its own features and benefits. There might
be a number of factors such as the frequency and length of the procedure worth
considering when making your decision but you always feel safer choosing a lead
free shielding alternative. After all choosing a material which has its own health
hazards to protect you from the health hazards of radiation does sound counter
intuitive
So Can I Really Breathe Free
Despite posing all kinds of health risks radiation is commonly used in several
radiologic applications not only for diagnostics but also for treating patients through
advanced treatments. Modern-day applications are able to deal with radiation
better and this is largely due to the advent of radiation shielding materials. While
these materials have literally transformed the field of medicine and helped in saving
countless lives the use of radiation i s n ’ t entirely free from risks. Those dealing with
radiation must understand how to protect the human body from radiation and also
receive the right training in preventing injuries to ensure patient safety.
