The Baba Atomic Research Centre (BARC) has developed a pulsed UV Disinfection System produces pulsed, high energy, broad spectrum of UV lights (200- 400 nm). The uniqueness of this system is its broad UV spectrum which can kill various pathogens having different DNA absorption peaks unlike the conventional UV-C lamp which produce a single peak of 254 nm. This system is tested at 1 meter which can kill 99.998% of pathogen when exposed for only 5 minutes. It can be used for sterilization of medical devices, food sterilization in food industries and installed in any transport devices like car, bus for disinfection purposes.
The Conventional methods for sterilization of medical devices like wet/dry heat, irradiation, chemical gases can negatively alter the material properties which influence the physical and biological performance of the medical device, which can lead to material failure. Similarly in food industries, traditional thermal-based food-processing methods for microbial inactivation changes in food matrix; such as structural alteration of proteins, production of free radicals, affects the functionality of food and flavour, destruction of colours and vitamins. Emerging technologies like UV light sterilization/disinfection can suppress the drawbacks of the conventional methods used in hospital and food industries .The developed pulsed UV disinfection system which produce pulsed, high energy, broad spectrum of UV lights (200-400 nm). Uniqueness of the system is its broad UV spectrum which can kill various pathogens having different DNA absorption peaks unlike the conventional UV-C lamp which produce a single peak of 254 nm. Pulsed UV light has many advantages over continuous UV light in terms of microbial inactivation efficacy, penetration ability, and lamp safety. This kind of Pulsed UV disinfection systems are already tested in abroad for quickly deactivate SARS-CoV-2, MRSA, C. diff, VRE and other pathogens.
A few applications of this technology include; the sterilization of medical devices and surfaces, UV food sterilization in food industries on conveyer lines and packaging materials, simple operation and portability of the system helps it to install in any transport device like car, bus for disinfection purpose, disinfection of small areas like school and Gyms.
