Due to the fact UV light-weight does not penetrate surfaces and will likely not pass through plastics or glass, cells should be exposed directly to The sunshine supply.
The NIOSH's quickly hazardous to lifestyle and wellness Restrict (IDLH) for ozone is 5 ppm, 160 occasions smaller sized compared to 800 ppm IDLH for ethylene oxide.
