VEST FOR PROTECTION AGAINST GAMMA RAY

PHOTONS

Patent No.: US08580029-B2; US2012/0304894-Al

INTRODUCTION

• The utilization of waste rubber powder in polymer matrices provides an attractive strategy for polymer waste disposal. In this research. lead free flexible composite material samples for anti- radiation purposes were produced. 25 wt% of recycled acrylonitrile-butadiene rubber (NBRr) were added to Natural rubber (NR) to prepare the composite's matrix part

• The matrix was incorporated with various hard materials wastes such as (iron particulates. iron fillings and slags) brought from different industry zones. The amounts of these added particulates were ranged from 15- 75 wt%.

• All fabricated samples were assessed for their anti-radiation attenuation properties, the attenuation measurements were performed using gamma spectrometer of Nal (TI) detector. The utilized radiation sources comprised 13'CS and "Co radioactive elements with photon energies of 0.662 MeV for 13'CS and two energy levels of 1.17 and 1.33 MeV for "Co.

PROBLEM STATEMENT

There are many byproduct materials of various industries represent a burden on the environment and ways to get rid of them need to waste a large amount of money, such as steel slag, iron filings, ball bearings components and other spin-offs that appear in industry.

• Development in many areas summoned the use of radioactive materials and the latter has to be preventable well because it is very harmful.

• The free-lead rubber shielding properties may vary depending on the composite constituent of the rubber blend.

• It Is therefore possible to use these materials consumed by mixing with rubber for the manufacture of armor vest for protection against ionizing radiation.

_ PRODUCT DESCRIPTION

• Disposal of metal by-products from various industries, which represent a burden on the environment.

• Incorporate these consumed substances into rubber blend to produce protective shields against the threat of certain harmful radiations from different sources.

• Addition of carbon based byproducts material (slags)from steel industry to improve anti radiation performance of the rubber composites.

::~) NOVELTY

• Blend of natural rubber, recycled rubber and heavy waste materials are used to fabricate green anti radiation armor vest.

• The invented material is flexible and can be arranged in the required shape that can be facility at the movement of the workers wearing this vest.

• Rubber NR/NBRr mixture with.jron particulates can be an effective candidate as radiation protection shield as opposed to the pure lead sample currentiy used in radiotherapy. These fabricated samples can be used for covering walls of nuclear stores. also as protection clothing in nuclear medicine departments and nuclear investigations centers and even to prevent astronauts from cosmic radiation etc. for anti damage against gamma-ray.

• Giving the opportunity to recycle huge amounts used rubber, metal particulates and slags to be utilized to fabricate useful part instead of been sent to the landfill.

• The prepared samples are characterized to be flexible and not to break at bending.

There is an inverse proportionality between ~ and radiation energy and direct proportionality with the samples overall density.
