Lead shielding refers to the use of lead to shield or protect people or objects from radiation. Because of its high density and high atomic number, lead can effectively fade certain kinds of radiation. Lead containers are designed for the storage and shipment of radioactive materials. In most of the cases, outer dimensions and appearance are almost same; the difference lies in the thickness of lead shielding.
Medi-Ray fabricates lead containers for radioactive pharmaceuticals, nuclear applications, radioactive source storage, and waste containers. All containers feature interlocking component designs that guarantee no radiation leakage and provide safety during handling and transport. From outside, these containers are plastics shelled, that protects you from physically touching lead, which is a toxic metal. Medi-Ray can design and manufacture these lead shielding containers in multiple sizes that can accommodate hundreds of lead wall thicknesses, cover designs, and locking mechanisms.
These lead shipping containers are manufactured from A36 or 44W carbon steel. All hardware used from heavy-duty hinges to locks is of the highest quality. Extreme care is taken in the surface preparation to all surfaces for the supply and application of a finish coat of paint to the desired color.

Employees who work in x-ray rooms and nuclear industries run a high risk of incurring diseases like cancer due to repeated exposure to radiation. To avoid such fatalities, several lead products act as barriers to shield radiation and protect people working with or around the radiation scattering equipment.
Lead is a dense metal with a high atomic number and it can shield against all types of harmful radiation x-rays, alpha-rays, and gamma rays. When you visit a medical facility, you can see that the x-ray technician moves behind a lead wall. You may wonder why the patient is not provided with the shielding material. This is because the patient may be exposed to x-ray radiation once or twice a year but the technician is exposed to the radiations repeatedly, maybe for several years because it is his job occupation.
Industries that deal with radiation also need to protect equipment from radiation. The equipment is shielded with lead casing or lead walls to control the intensity of radiation. Radioactive materials are stored in lead containers and radioactive waste is disposed of in lead bins. Lead containers are also used to transport radioactive materials. The lead transportation containers are specially designed to avoid any breakage or leakage during transportation.

Lead – Best Radiation Shielding Metal
Lead is the best metal in providing protection from various sources of radiation. It has become a standard in the design of Radiation Protection systems. Lead shielding refers to the use of lead to shield or protect people or objects from radiation. Because of its high density and high atomic number, lead can fade certain kinds of radiation. And that’s why lead is used as radiation protection in applications ranging from x-ray imaging and PET rooms to nuclear reactors.
Criteria for Selection of Shielding Material
Thickness is not enough for a material to attenuate radiation. There are certain characteristics that are required in a material to use as radiation shielding.
- Shielding material should have high density and high atomic number, which in turn is better attenuator of x-rays and gamma rays.
- Shielding material should have good heat conductivity.
- Shielding material must be resistant to radiation damage.
- Shielding material should have required thickness and weight.
Apart from the above characteristics, you should also consider the cost of shielding material, transportation and installation. Also, take into account its wastage and scrap value; and availability and ease of shielding material.
Properties of Lead as Shielding Material
The properties of lead are its high density, high atomic number; high level of stability, ease of fabrication and availability makes it excellent shielding material.
- Lead has extremely low-level neutron absorption and practically no gamma radiation. It cannot become radioactive. Even after long exposure of neutrons, lead emits an insignificant amount of radiation due to activation.
- Lead is not too dense, but it is readily available, easily fabricated and is less expensive than other high-density materials.
- Lead is more uniform throughout as compared to other materials.
- Lead is less likely to become contaminated with dirt, which in turn may become radioactive.
- Lead can be immediately available for reuse, adaption or for sale as scrap.
Forms of Lead Available For Radiation Shielding
For radiation shielding various forms of lead are used. The shielding of containers for radioactive materials is usually metallic lead. Radioactive materials in laboratories and the medical industry are usually handled by remote control from a position of safety. Personal shielding includes lead aprons (such as the garment used during dental x-rays), thyroid shields, and lead gloves. There are also shielding devices available for laboratory equipment, including lead castles, structures composed of lead bricks, and thick containers for storing and transporting radioactive samples.
We understand why lead is the best shielding material. Mediray is devoted to innovation in lead metal technology as it mainly deals with shielding of X-ray, CT, PET, MRI equipment.
Radiation Protection, otherwise known as radiological protection, is the science and practice of protecting people and the environment from the harmful effects of Ionizing Radiation. Ionizing radiation is used in many aspects of industry and medicine, and as a result can present significant health hazards. Such radiation causes microscopic damage to body tissue, which can lead to skin burns and radiation sickness at high exposures, as well as heightened risks of Cancer at low exposures.
Radiation protection is divided into a number of different categories, as there are many different factors to consider when it comes to protecting individuals from radiation, as well as keeping their surrounding environments radiation free.
Radiation exposure is managed by a combination of three factors, these being time, distance, and shielding. Time refers to reducing the amount of time that individuals spend exposed to radiation equipment, while still ensuring that patients receive their appropriated dosage. Distance, refers to increasing the distance between radioactive equipment, and the individuals surrounding it. Finally, shielding refers to absorbing material placed around radioactive sources, to reduce the amount of radiation to a level that is safe for humans. Types of 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.
Counterweights come in many different sizes, shapes, and materials, and in accordance, are used for many different things. However, the most important need for a counterweight is to create a sense of balance. In terms of Aeronautical Counterweights, their use is to keep airplane pilots from over exhausting their aircrafts.
Aeronautics is the science involved with the study, design, and manufacturing of air flight capable machines, or the techniques of operating aircraft and rocketry within the atmosphere. Counterweights used in this regard, are also known as bob weights. Their main purpose is to change the amount of control force required to deflect an airplane’s control column. This process is dependent on the factor of air speed.
By installing lead counterweights into aircrafts, aeronautical engineers can make it more difficult to pull on the control column as g-force increases. G-force is the force to which a body is subjected when accelerated. The installation of lead counterweights in aircrafts is an important safety procedure, as it ensures that a pilot will not overstress his aircraft.
Medi-RayTM‘s skilled team of craftsmen pride themselves on the production of such counterweights, as well as many others with a wide range of sizes, material types, and uses.
Radiation has wide ranging uses in day-to-day life. In medicine, there are many uses for radiation like x-ray, mammography, computerized tomography (CT), cardiology and nuclear medicine. Treatment of disease or cancer by chemotherapy uses radiation.
The wide ranging use of radiation in medicine poses the challenge of shielding radiation exposure to parts of the body other than where where it is intended. Also, doctors, relatives and friends of patients or others who have to be associated with the place where radiation is exposed or radioactive materials are stored or transported need to be protected as well.
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.
Why Does Lead Work for Radiation Shielding?
Lead has high density, a result of the combination of its high atomic mass and the relatively small size of its bond lengths and atomic radius. The high atomic mass means that more electrons are needed to maintain a neutral charge and the small bond length and a small atomic radius means that many atoms can be packed into a particular lead structure. Because of lead’s density and large number of electrons, it is well suited for scattering x-rays and gamma-rays. These rays form photons, a type of boson, which impart energy onto electrons when they come into contact.
Lead is used for shielding in:
• X-ray machines
• Nuclear power plants
• Labs using radioactive materials
There are also a variety of shielding products used to protect people, shield equipment and experiments, such as:
• lead aprons
• thyroid shields
• lead gloves
• lead bricks
• leaded glass
• leaded glass sheets
• lead clad building material
• lead laminated panels
• lead sheets
• lead foils
