High Energy Radiation Shielding Textiles

Technology Overview

This technology presents a method to produce good protection textiles that shield high energy radiation. Current radiation protective clothing is heavy and bulky, which not only reduces the dexterity and flexibility of the wearer, but also makes the wearers feel tired easily and suffer from certain health problems over long-term wearing.

The newly developed materials are softer, lighter and more efficient in shielding radiation when compared to the existing protective wear. In addition, this is a green technology which does not need any solvent to produce and the materials themselves are recyclable.

Technology Features & Specifications

This technology consists of two steps to functionalise the elastomer protective clothing with safe micro-particles. The shielding textiles are fabricated by this two-step process:

  1. Melting spinning of composite fibres
  2. Melting networking process

The linear attenuation coefficient (amount of X-ray or gamma radiation absorbed or scattered) was found to be significantly higher in the new textile than lead rubber used in traditional protective clothing.

This demonstrates that the new textile has better X-ray shielding effect than commercial lead based protective clothing. Furthermore, the density of the new textile is lower when compared to lead rubber, which explains the lighter weight of the new invention.

Potential Applications

This technology is applicable in (but not limited to) the following industries:

  • Wearable protective vests, aprons and accessories for use in establishments where X-ray equipment is operated or radioactive materials are used, e.g. hospitals, clinics and laboratories
  • Portable X-ray shielding curtains on equipment or for specific areas, e.g. airport security channels and nuclear power stations

Customer Benefits

  • Lighter in weight than existing lead-containing protective clothing, which enables the users to wear for a longer period of time, to allow better compliance to radiation shielding
  • Softer and more flexible than existing rubber protective wear
  • Protective garments with desirable designs can be produced
  • Washable
  • Recoverable materials were used, which enables recycling
