Why is lead used for protection from radiation?

X-rays, CT scans, MRI scans and other radio pharmaceuticals equipment are used to detect improper functioning of internal organs and to cure certain diseases. However, overexposure to the radiations emitted by these types of equipment can be dangerous. Therefore, to regulate the intensity of radiation scattered by these equipment, they are shielded with lead.

One primary property of lead that makes it ideal for shielding material is its density. Other properties such as its high degree of application flexibility, extreme level of stability, and high atomic number also make it ideal for radiation shielding.

What are the various types of foam tape?

There are three types of foam tape:

Single Coated Foam Tape

Single coated foam tapes have adhesive coated only on one side. They are made from many different materials that are used in a wide range of gasketing and weatherproofing, shiming, protective packaging applications. They can also be used for noise and vibration cancellation. Single coated foam tapes are available in many different widths and thicknesses. They serve to seal or separate two surfaces without actually bonding them together.

Double Coated Foam Tapes (Non-transparent)

Double-coated foam tapes are designed to provide superior adhesion to a wide range of surfaces. The thickness of the foam lets it fill in any imperfections in the surface its being applied to. They are available in almost any width as well as several thicknesses to suit any application.

Double Coated Clear Foam Tapes

Clear foam tapes are the perfect way to join glass and other clear rigid plastics without seeing the tape. They can be cut to any width or die cut into custom shapes for ease of use in production. They also work great on colored plastics, smooth metals, and painted surfaces.
