A CFL bulb is made of glass, a ceramic and metal base, a powder called phosphor, and a small amount of mercury. The mercury in the bulb is in the form of an invisible vapor or as part of the phosphor coating on the inside of the glass. CFL bulbs use less energy than a regular light bulb.Persons in rooms after breakage of a CFL may be exposed to mercury by inhalation and by oral intake. After inhalation, more than 80% of inhaled Hg0 vapour is absorbed by the lungs.Keep a window or door to the outdoors open; Vacuum the area where the bulb was broken using the vacuum hose, if available, and. Remove the vacuum bag (or empty and wipe the canister) and seal the bag/vacuum debris, and any materials used to clean the vacuum, in a plastic bag.

Do CFL bulbs emit radiation?
Since CFLs are designed to provide general illumination, the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.
