Lead aprons are a protective layer of lead worn over the body in order to shield X-rays from penetrating the body. Lead aprons can absorb up to about 95% of any scatter x-rays that may be hitting the wearer.
Anyone wearing a lead apron must also have a dosimeter badge. If given two badges, one is to be worn under the apron and one is to be worn outside the apron on the collar. These badges are labeled accordingly and should be worn correctly, this allows for an accurate dose estimate to be made.
If the badges are worn incorrectly, a proper dose estimate cannot be made. Please remember to check the badges to make sure you are wearing them properly.
Also, do not store your badges on the lead aprons themselves. After using a lead apron, make sure to hang the apron so that it is not creased.
Do not store the aprons folded or crinkled on a counter or table. This can cause cracks in the lead and can compromise the effectiveness of the apron.
