Shielding means creating a barrier between a radiation source and the thing or area to be protected. The ultimate purpose of nuclear radiation shielding is to control or limit the exposure rate of nuclear radiation.
What is Shielding? Why is it Needed?
Shielding is a gradual reduction or attenuation in the intensity of nuclear energy through a medium. Shielding materials absorb and decrease the radiation that passes through them. This is how exposure to radiation gets reduced for the other side of the barrier to remain protected.
The radiation workers in nuclear plants, nuclear submarines, medical facilities, dentists, and workers of nearby offices would get exposed to high levels of radiation without shielding. That would affect their health. Nuclear radiation can't be zeroed but can be reduced to a great level.
Shielding Materials
The most effective nuclear radiation shielding product is lead. Its high density makes it the strongest barrier against gamma-ray and x-ray radiation. It is also easy to process and cheaper.
Apart from lead, other materials offering protection from radiation are water, concrete, air stops and special plastic shields.
Medical and other fields generally use lead shielding, lead-free, and lead composite shielding. All three types of shielding have their pros and cons.
Lead Shielding- The Traditional Procedure
It's ideal for long-term shielding as it is available, soft and corrosion-resistant. It is made durable and flexible with mixing materials like vinyl.
Traditional lead materials are widely used for their diversified benefits. But they are toxic and have health and environmental hazards.
Lead Composite Shielding- Known for its Longevity
Lead composite shielding requires the mixing of lighter materials with lead. These materials are lighter but offer the same protection level. They are known for their longevity.
Lead-free Shielding: Emerging in Popularity
Lead-free composite, polymer-metal and nontoxic materials used for shielding are cost-effective and efficient. Therefore, these types of materials are gaining more popularity than lead shielding currently. They eliminate the harm that comes from lead materials.
The same composite technique is used but without lead. These materials are customizable, high-density, flexible, and durable. Most significantly, lead-free composite shielding are very eco-friendly.
Shielding Products: An Overview
Nuclear radiation shielding products are essential for construction activities at nuclear power generation plants, as well as nuclear submarines. The proper shielding materials made by experts of renowned brands contain harmful radiation and ensure protection for the workers from exposure.
Choosing The Right Products
Choosing the appropriate nuclear radiation shielding products is crucial, but the task is complex, with several considerations. You must consider the time, shielding, and distance, among other things. There are several standards to manage radiation exposure in nuclear power plants effectively. Those are as follows: -
-
Reduction in radiation exposure time
- Preventing or decreasing radiation doses by utilizing the nuclear shielding to the fullest
- Increase in radiation exposure distance
