“As indicated by Parker, chemical actinometry has several advantages when compared with radiometry for measuring UV radiation.”

“The kit includes 2x cells for test substance, and 2x cells for Quinine Chemical Actinometry as well as comprehensive Standard Operating Procedure documentation.”

“The ferrioxalate actinometer is a photon counter and is sensitive to wavelengths less than 450 nm.”

“A very suitable instrument for timing the exposure of carbon tissue is Sawyer's actinometer.”

“We then shift the paper in the actinometer so as to get a fresh portion under the tissue strips, or we substitute a new piece.”
