Lead Bricks for Effective Radiation Shielding

Lead bricks originate from the purest lead available and are popular for constructing lead walls in places where the need for radiation protection is high. Lead bricks are common in nuclear reactors to shield high intensity radiation produced in them.

Lead Bricks

Medi-RayTM provides lead bricks with interlocking features. The different types of lead bricks supplied by Medi-RayTM are:

Standard lead bricks

This is the basic type of rectangular lead brick. Medi-RayTM manufactures standard rectangular lead bricks of different sizes and thicknesses based on customer’s requirements.

Interlocking lead bricks

Interlocking lead bricks provide the highest level of radiation protection. They are used for building lead walls, and for fitting corners of lead walls and built using standard rectangular lead bricks.

Dura Block lead bricks are one of the types of interlocking lead bricks manufactured by Medi-RayTM. This brick can create a wall but cannot fit corners.

Lead barrier walls and caves

Medi-RayTM manufactures and pre-assembles custom lead walls according to the requirements of the customer. They can be directly installed in the area where radiation protection is needed.

Uses of lead bricks

  • Defense industry
  • Nuclear power plants
  • Laboratories where radioactive experiments are performed

If you need lead bricks or any other type of radiation shielding product contact Medi-RayTM at 877-898-3003 today.

Lead Shipping Containers for Radiation Protection

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.

Lead Shipping Containers

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. All storage containers are available with your choice in lead shielding from 1/32″ to 2″ thick or more.

Medi-Ray offers “just-in-time” delivery schedules for its clients to reduce customer inventory costs and to deliver mutually economical delivery quantities. Medi-Ray maintains a safety stock of castings, components, and finished products to guarantee timely delivery.

Lead Shielding Offers Radiation Safety Solution

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 Shielding

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.

Medi-Ray is a leader in the manufacture of radiation shielding products. They have been developing lead radiation shielding components since 1970. If you need radiation shielding products for your industry, contact Medi-Ray at 877-898-3003.

X-Ray Shielding: Medical Radiation Protection

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.

Mediray has developed clinic, laboratory, and medical office products for various types of x-ray applications, using such materials as lead castings, sheet lead, and lead foil.

Lead Radiation Shielding

Lead Radiation Shielding

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 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.

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
•    Hospitals

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

•    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 Bricks

Lead bricks and interlocking lead bricks are be used for adding extra shielding to existing rooms. The Lead bricks produced by Medi-RayTM feature non-porous surfaces, which are clean and smooth. Our bricks are also brightly painted creating a wall which is safe and pleasant to the eye.

Other uses for lead bricks include nuclear shielding, radioactive material shipping containers, ballast weight, and glove boxes. Medi-RayTM prides itself in meeting unique client specifications and requirements in the construction of lead bricks and interlocking lead bricks.

Interlocking lead bricks are used in applications where the highest protection level of shielding is needed from Gamma, Beta and X-ray radiation. Interlocking lead bricks can be easily assembled, modified, deconstructed and relocated in various situations where protective cells and wall systems are required. We can also design these using specific customer applications.

An advantage to interlocking lead bricks is their ability to prevent the leakage of radiation through spaces which are generally found in straight lead bricks. In addition, the interconnecting feature of interlocking lead bricks results in a sturdier and more stable wall system, ensuring that the wall created is firm and strong.

Medi-RayTM has lead bricks and interlocking lead bricks available in a wide range of dimensions and weights for every customer’s requirements and specifications. Along with lead brick and interlocking lead brick capabilities, Medi-RayTM has many other custom services available.
