Types of Lead Shielding Instrument Commonly Used

Alpha particles (helium atoms), X-ray radiation, beta particles (electrons), and gamma radiation are all blocked or attenuated by radiation shielding (energetic electromagnetic radiation). By adding a radiation-absorbing material, it lowers the intensity of incoming radiation. The radiation shield’s efficacy is determined by the material and thickness of the shield.

 

Specifications

The following are some of the radiation shielding specifications:

  • the thickness of material (e.g., tungsten, lead), substance purity (99.94 percent lead, etc.)
  • blocked or reduced radiation’s rated energy range (100 to 300 keV)
  • Liquid-cooling and application features are also essential to consider.

Standards

Organizations like Underwriters Laboratories (UL) and Underwriters Laboratories Canada identify or approve several radiation protective products (ULC).

Types

Radiation shielding comes in a variety of shapes and sizes. Most of the goods are composed of lead, a bluish-white heavy metal with a high density that can efficiently attenuate alpha, gamma, and X-rays. Lead shielding, which includes lead aprons, is a kind of radiation shielding.

  • Barriers made of lead
  • blankets with a lead lining
  • curtains made of lead bricks
  • Cabinets with lead lining
  • doors with a lead liner
  • sheets of rolled lead
  • apron with lead lining

Medical staff and patients use lead aprons during X-ray treatments as a kind of protection. Lead barriers and blankets are used to protect patients and medical equipment from lead poisoning. 

Shielding for positron emission tomography (PET) and linear accelerators is done using lead bricks. In addition to gamma knife rooms and high dynamic range (HDR) imaging, these radiation shielding solutions are utilized in gamma knife rooms. 

What Works Together with Lead Line Cabinets

Radiation shielding goods such as lead drapes, lead-lined doors, lead-lined cabinets, and rolled lead sheets are also made of lead. Lead curtains with a vinyl lining are intended for use in medical institutions with secondary or low-level radiation. 

A track and trolleys may be included with lead-lined curtains. Radioactive material and other radioactive inventories are stored in lead-lined cabinets as well as other lead-lined laboratory equipment. 

Lead-lined doors feature a thick layer of lead sheeting in the middle and are faced with wood. A slab of refined lead is rolled between the rollers of a rolling mill to produce rolled lead sheet.

The rolled lead is packaged and sent to providers of radiation shielding for use in different products after the sheet is trimmed to size. Lead is inefficient against the high-energy electrons seen in beta and neutron radiation, despite its widespread usage in radiation shielding. 

As a result, in particular medical and laboratory applications, high-energy shielding is needed. High-energy protected decay drums, for example, are employed to keep high-energy radiopharmaceuticals safe. 

A mirror-polished and scratch-resistant barium-type lead glass and X-ray shielding glass, used at airports and other radiation screening facilities, is also included in nuclear medicine supplies and accessories.
