Considerations for Lead Shielding

A certified professional radiation health physicist must calculate the proper amount of lead shielding required based on certain considerations. It will depend on the source of radiation—the type of machine used and where it is located. The following information helps in understanding what factors determine lead shield requirements for diagnostic imagining and radiation therapy. The goal is to ensure that the maximum radiation protection is achieved.

Lead shielding requirements are calculated and determined based on the following considerations:

  1. Energy potential: The energy potential of the machine will determine the lead shielding requirement—the higher the output of the machine, the higher the lead shielding required.
  2. Workload: The exposure per week, month or year must be determined, as well as the maximum patient volume growth, as radiation is cumulative and overexposure causes biological damage on the cellular level. Check the local governing health and safety law and codes for current compliance requirements.
  3. Orientation/Direction: Wall lead shielding is calculated by a physicist in relation to the primary beam target. The direction where the radiation is aimed and will scatter.
  4. Distance: Radiation will dissipate more as distance increases. The closer a partition is to the radiation/x-ray source, the higher the shielding requirement.
  5. Occupancy: A very important part in your calculation is the amount of time, per day, a surrounding room similar to the x-ray room (source or radiation) will be occupied by personnel or public. The lead shielding on wall and floors increases with the level of occupancy.
  6. Type of material: The type of construction material used for wall, partition and floor may reduce the requirement for lead shielding. Heavy density materials such as concrete, steel and plaster can shield radiation to some level.

All lead shielding requirements should be calculated by an expert.

Lead Shielding And The Medical Industry

For many years it has been thought that lead is a very dangerous material that should be avoided or removed from peoples’ homes. Nobody ever expected that lead would be used for something good, something that could save lives. Today lead is used to make protective shields. Lead shielding has many uses in a variety of different industries. However, its most common and important purpose is to create a protective shield for patients undergoing X-Ray testing or radiation treatment. If you or someone you know is in need of lead shielding, or is interested in learning more about it, contact Medi-Ray™ today. We have the professional knowledge and experience to make sure that our customers are completely satisfied with their safety material.

Due to lead’s high density, it is the perfect material for blocking gamma rays and x-rays that can be harmful to the body, as they can tamper with DNA and even cause cancer. However, with the protection of lead shielding, harmful rays are absorbed in the lead and never even make it to the body.

Lead shielding comes in many forms, shapes and sizes. For example, lead shielding can be found in the form of an apron for patients to wear in an x- ray testing room, to cover sensitive organs in the body. Lead shielding can also be found in the laboratory itself, in structures such as walls comprised of lead bricks, as well as thick containers with a lead base, used for transporting hazardous radioactive materials.

If you or someone you know is in need of lead shielding or would like to learn more about it, contact Medi-Ray™ today. Our experienced team of professionals will stop at nothing to make sure that our customers are satisfied and that all their needs are met.

Nuclear Medicine/Radiopharmaceuticals Market by Type , Therapeutic & by Application – Global Forecasts to 2020

Over the years, the nuclear medicine/radiopharmaceuticals market has witnessed various advancements. The global nuclear medicine/radiopharmaceuticals market is growing due to the increasing number of radioisotope approvals for different clinical indications. Tc-99m and F-18 are estimated to be the highest contributors to the nuclear medicine/radiopharmaceuticals diagnostics market; whereas, Ra-223, I-131, and Y-90 are estimated to be the highest contributors for the nuclear medicine/radiopharmaceuticals therapeutics market in 2015.

Medical Isotope Generators Are Essential for Nuclear Medicine Market

In the nuclear medicine market medical isotope generators are used to produce many regular used imaging isotopes. Gallium-68 and Technetium-99 generators are extremely radioactive and need to provide shielding, which is generally composed of either lead or tungsten. Without proper shielding these radioactive generators cannot be shipped or used in their applications.

Which Metals Are The Best Shielding Solutions

Radioactive generators require shielding, which is usually composed of either lead, tungsten or a combination of both metals to provide the best shielding solutions.

Tungsten, Lead or a Combination?

  • Density wise, tungsten has a higher density than lead. Lead has a density of 11.34 g/cc; tungsten has a density of 17.3 g/cc.
  • The cost of tungsten is around 25 times the price of lead because of the material difference and the processing needed.
  • Tungsten is a tougher shield than lead.
  • A hybrid or a combination of both the metals along with some other materials is the best option, as they prove to be more functional and produce cost effective results.
