X-Ray Shielding- Medical Radiation Protection

Radiation protection is practice of protecting people and the environment from the harmful effects of radiations. Ionizing radiation is used in many aspects of industry and medicine, which can result in significant health hazards like damage to body tissue, which can lead to skin burns and radiation sickness at high exposures, as well as risks of cancer at low exposures.

There are three types of radiation safety measures that must be taken to control the dose or amount of radiation from x-ray equipment. These include:

- Reducing the time of exposure as this reduces the dose proportionally.

- Increasing distance to reduce dose. This can be done by making use of forceps to handle a source rather than using the fingers.

- Shielding to reduce radiation to a level that is suitable for humans. Shielding can be done by placing a mass of absorbing material around the radioactive source.

Among the above safety measures, shielding the x-ray equipment to reduce the level of radiation using lead radiation shielding products is the best way.

Lead radiation shielding

Shielding may include lead sheets in the walls surrounding an x-ray room, lead glass or screens on the viewing room for operator safety, and lead aprons for patients to wear. The effectiveness of such shields depends on shield thickness. Lead is used to produce X-Ray shielded products ranging from lead syringe shielding, shipping containers, laboratory accessories, lead sheet, lead bricks etc. X-Ray shielding can be done using lead sheet of 2 mm thickness. Mobile X-ray barrier can be mounted on wheels and moved around easily. This is used extensively in medical industry. Patient is exposed to controlled intensity X-ray for some time while the doctor stays behind a curtain.

This safety measure is taken as doctor will do the producer on many patients. Regular exposure to X-Ray is dangerous to health. Lead containers are available now a days for shielding instruments form x-rays. Everything in X-Ray room is X-Ray shielded. Radiation shielding for syringe is available in the market.

Forms of lead used for radiation shielding

Lead has long been recognized as a highly effective material in providing protection from various sources of radiation, and as such, has become a standard in the design of radiation protection systems. Lead shielding refers to the use of lead to shield people or objects from unintended radiation.

Lead can effectively contain certain kinds of radiation because of its high density and high atomic number; principally, it is effective at stopping alpha rays, gamma rays, and x-rays.

Different forms of lead used for radiation shielding

Lead Laminates

Sheet lead that is bonded to other materials such as wood, steel, wallboard, plastic, and aluminum for the manufacture of panels, doors, cabinets, portable screens, etc., is known as lead laminate.

Lead Sheet

Sheet Lead is one of the most malleable of common metals. Sheet lead is very effective for waterproofing, soundproofing, and isolating mechanical vibration. It is highly resistant to environmental and chemical corrosion, and so can be used in nearly any indoor or outdoor application. Lead sheet is exceptionally versatile and easy to work with.

Lead Plate

Lead Plates can be composed of 99.9 pure lead or antimonial lead. These plates are molded from precision high-strength steel molds and can be machined to exact dimensions.

Lead Brick

Lead bricks are typically used in nuclear and radiation therapy applications. However, lead bricks can also be used for radioactive isotope creation, ballast weights and counterbalances. The interlocking feature of these lead bricks eliminates any radiation leakage in the wall. These interlocking lead bricks are offered in sizes that are manageable and easy to stack, and they require no mortar or any other additional shielding materials.

Lead glass

To provide viewing of the patient in the x-ray room while providing protection to the operator, lead glass viewing windows can be furnished in the barrier. It is produced 1/4 inch thickness which is equivalent to 1.5mm sheet lead. Lead glass can be installed in multiple layers so as to provide a lead equivalency to the lead in the wall in which it is installed.

Lead Foils

Lead Foil is a form of lead sheet that is thin enough to be easily cut and formed using shears. Lead foil can be stamped or formed into almost any shape so that it can be placed around any area that needs protection. Lead foil is often supplied backed with pressure sensitive adhesive or vinyl to aid the application of the product.

Lead Gloves

Used to store larger quantities of radioactive pharmaceutical inventories, these Glove Boxes are designed with stainless steel ergonomic handles, precision hinges and finely counterbalanced doors. They permit one-handed fingertip operation, which helps the rapid selection and removal of radio pharmaceutical vials and minimizes the clinicians' exposure.

Lead Clad Tubing

Lead clad tubing is used for shielding of radioactive materials

Lead Wool

Lead wool is used for filling deep cracks in a radiation barrier

Lead aprons

Lead apron is used to provide protection against harmful x rays, which is widely used in diagnostic departments of hospitals and varied other medical institutions.

U.S Lab Develops Three New Neutron Shielding Products

Every day, protecting sensitive scientific equipment and computers from radiation is becoming a challenge for engineers at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility. So, they have developed three innovative products that could soon find their way to nuclear power plants, particle accelerators and other radiation-generating devices around the world.

A senior consultant from Mediray^TM1 discusses about Nuclear Medicine Shielding accessories that they supply, “Medi-Ray^TM has been the largest supplier of radio-pharmaceutical shipping containers since 1974. Medi-Ray^TM founders were the driving force in the development and refinement of shielded laboratory equipment and accessories for nuclear medicine. Our line of products includes numerous vial shields, syringe shields, and specialty items. Design staff personnel can develop an entire series of accessories to complement a radio-pharmaceutical product line.” (Ref: Mediray^TM, http://www.mediray.com/product_category/products/nuclear_medicine_accessories)

The three patented/patent-pending technologies form a system for shielding that is less expensive, lighter and less bulky than standard products and easily manufactured using existing techniques. They consist of recipes for a lightweight concrete that is four times better at slowing down neutrons than ordinary concrete, a boron-rich concrete that absorbs neutrons using less material, and a thin, boron-rich paneling for use in space-restricted areas. The ability of a system built using these technologies to block radiation, particularly neutrons, has applications in the storage of nuclear waste, in building compact nuclear reactors and in shielding radiation sources used in medical applications.
