High Density Radiation Shielding Concrete Applications in

High density radiation shielding concrete is produced by blending heavy weight aggregate, cement, water, and special additives. Applications of radiation shielding concrete is discussed. Aggregates for high density concrete for radiation shielding are iron shot and steel punching which are utilized to produce substantially high dense concrete.

Neutron Shielding Properties of Concretes Containing Boron

Concrete is the most generally used shield material as it is inexpensive and adjustable for any construction design. Radiation shielding properties of concrete may vary depending on the concrete composites. Different types of special concrete have been developed by the addition of shielding material such as iron and boron carbide in aggregate

Physical-radiation shielding properties of concrete

As the concrete is a widely used construction material, the mechanical and radiation shielding properties of concretes containing boron-bearing aggregate additives have been studied. The results show that the addition of colemanite or ulexite into concrete has significant effects on density, workability, compressive and flexural strength

PDF Basic Principles of Radiation Therapy Shielding Design

The purpose of radiation shielding is to reduce the effective equivalent dose from a linear accelerator to a point outside the room to a level that is determined by individual states. Public or uncontrolled area - 0.02 mSv per week - 0.02 mSv in any one hour Controlled area - 1 mSv/wk (in practice 0.1 mSv/wk)

Effect of Flyash Addition on Mechanical and Gamma

Six concrete mixtures were prepared with 0%, 20%, 30%, 40%, 50%, and 60% of flyash replacing the cement content and having constant water to cement ratio. The testing specimens were casted and their mechanical parameters were tested experimentally in accordance with the Indian standards. Results of mechanical parameters show their improvement with age of the specimens and results of radiation

PDF Concrete mix design for X-and gamma shielding

Concrete is not as effective in shielding radiation but it is a very common building material and so it is commonly used in the construction of radiation vaults. Most designers and builders today are familiar with the advantages of using very high density concretes for radiation shielding. Not so well known is the excellent economy which can

THE WATER CONTENT OF HARDENED CONCRETE. Final Report

The feasibility of simulating ground motion produced by a nuclear detonation in or near the ground surface was established. In particular, the simulation of the physical input necessary to produce the ground motion in a restricted volume sufficiently great to encompass a buried structure was investigated.

Ducrete - Wikipedia

This ceramic material is a very efficient shielding material since it presents both high atomic number (uranium) for gamma shielding, and low atomic number (water bonded in the concrete) for neutron shielding. There exists an optimum uranium-to-binder ratio for a combined attenuation of gamma and neutron radiation at a given wall thickness.
