Bel-Art Autoradiography Pen; High Energy Level, Non-Radioactive

Autoradiography Pen; High Energy Level, Non-Radioactive 

Excellent for marking various radiography substrates with run numbers, dates, exposure times, film alignment markings, etc., these non-radioactive markers incorporate a non-toxic, solid, phosphorescent material that will not leak or dry out.

• Bright green markings do not emit Beta or isotope particles; markings do not glow in the dark
• Markings are visible under normal conditions; will show up on X-ray film
• Spectral peak is 5600 Angstroms
• Emission of non-radioactive energy may be adjusted by exposure to normal incandescent or fluorescent white light
• 3 to 4 minute energy emission leaves a distinct impression; will not overexpose film as some products do • Choose from normal or high energy level pens
• Length: 11.4cm (4½”); includes pocket clip
• Not appropriate for phosphor screens
• High Energy Level Pen has higher signal emission strength and a slightly longer duration of signal emission time
• High Energy Level Pen is best used for marking X-ray films similar to Kodak XLS; works well when film responsiveness is lowered as with chilled films which often require intensifier screen techniques
