The Frisker (Ludlum 26-1) is described as detecting which radiation types and used for what purpose?

• A. Only gamma radiation
• B. Alpha, Beta, Gamma radiation; Used for decon
• C. Neutron radiation
• D. Ultraviolet radiation

Answer: (B)

The Frisker is a handheld survey instrument designed for surface contamination checks. It is capable of detecting alpha, beta, and gamma radiation, which are the common forms of ionizing radiation you need to identify when cleanup or decontamination is involved. Detecting all three types lets you locate contaminated areas on surfaces so workers can scrub them effectively and prevent spread. It isn’t used for neutrons, and ultraviolet light isn’t ionizing radiation in this context, so those are not what this device is designed to detect.
