FAQs
Some of the frequently asked questions on radiation protection apparel are listed below. For any other questions and queries, please contact us.
What is lead equivalence?
Lead equivalence is the equivalent thickness of lead metal in the radiation protection apparel.
How is lead equivalence measured?
Measurement technique is outlined.
What is the correct Lead Equivalence required in various radiation protection apparel?
Commonly used lead equivalence is 0.5 mm Pb as recommended by radiation safety standards set by most of the regulatory authorities in the world. However, 0.35 mm Pb and 0.25 mm Pb are the other standards particularly followed in Europe.
Why should radiation protection apparel be used?
It is an essential safety requirement for prevention against radiation hazard. Non-use of radiation protection apparel can have severe health consequences.
What is the measure of performance of radiation protection apparel?
It should be lightweight for the required level of lead equivalence.
It should be designed for comfort, meet safety standards and be able to raise the solemn ambience of an X-Ray laboratory.
Why are multiple layers of lead vinyl or rubber used in radiation protection apparel?
If there are pinholes in a lead sheet due to any manufacturing defects, it is covered by a second layer at the same spot.
It is unlikely for a pinhole to occur at exactly the same place in 2 or more layers.
This ensures at least a partial protection in the unlikely event of a pinhole.
What is the expected useful life of radiation protection apparel?
Radiation protection apparel should be typically usable for 3 years. It should be inspected every year.
What is lead particle migration and its effects?
The movement of lead particles in a lead vinyl or rubber sheet will result in decreasing lead equivalence at some locations, while increasing it elsewhere. The lead particles must be correctly locked in the compounding process to prevent migration.
