笔 Autoradiography Pens
Ideal for marking various films that are to be X-rayed with serial numbers, dates and exposure periods, film position markings, etc. The marker has no bladder and does not contain any vials, thereby avoiding the risk of liquid spillage. Vivid green markings become observable under normal light conditions. These markings are not luminous in the dark but will be visible on radiography film. The markings have a spectral peak at 5600 Angstroms. Normal incandescent or fluorescent white light may be used to alter non radioactive emissions. Energy emissions are 3 to 4 minutes long and leave a marked impression without over exposure like generic products do. The pen features a handy pocket clip and is 114 mm in length. The writing tip is easily advanced by the screw knob. Reversing the screw knob and depressing the tip results in the retraction of the writing tip.
