RADAC lead markers are available in two styles: sharp face and flat face.
Sharp face markers are generally used for x-radiography and produce a well-defined, clean image on the film.
The flat face style has a greater bulk for use with the more penetrating gamma radiations.
Markers are supplied either unmounted or mounted to 0.73mm thick, rigid white PVC for easy handling.
The charcters available are arrows (sharp face only), capital letters and numerals.
Sharp face markers are measured with reference to the front, sharp face of the character. Flat face markers are measured on the back of the character. Sharp face markers are always, therefore,larger than the flat face characters of the same nominal size.
