In this fun & insightful science experiment, we decided to test a full-on blast of UV-C light against E. coli sample evenly distributed across a petri dish agar medium.
We've tested the UV-C exposure against incrementally higher doses of UV-C set to 15 seconds, 30 seconds, 1 minute, and 2 minutes respectively.
You'll note that at just while 15 seconds of UV-C exposure led to limited anti-microbial sterilization, just 30 seconds already killed almost 99% of visible colonies from replicating (and thus causing potential harm).
At 1 minute, only 2 colonies survived.
And lastly, at 2 minutes of exposure to UV-C NO growth colonies were visualized--- Wow!
Stay healthy and stay hopeful.
