2015: The International Year of Light
by Eugenio Silvestrini, Senior Health Physicist

Did you know that in December, 2013, the UN General Assembly proclaimed 2015 as the International Year of Light and Light-based Technologies?

IYL 2015 is focusing on raising global awareness about light-based technologies, promoting “sustainable development and provid[ing] solutions to global challenges in energy, education, agriculture and health.” Light–based technology has revolutionized medicine, communication, economics and the global society.

At Columbia University, light-based technology is used every day to advance these aims. Columbia researchers and clinicians use laser technology for crystallization of silicon films, photoacoustic imaging, cutting and bending materials, in scattering studies and glass scrubbing. To help support the evolving applications of laser and light-based technology and the potential safety challenges each application presents, EH&S has grown its Laser Safety Program to include enhanced audits, new guidance materials and additional resources to help ensure lasers are always used in a safe manner. Please check back soon for access to these items and other information.

So, the next time you turn ON a switch, surf the internet on your mobile device or gaze at the stars, take a moment to think about how light has changed your life and celebrate the International Year of Light!  

Fire Prevention Week is October 4-10, 2015
