THORIUM SAFETY
Thorium Safety
•
This laser system incorporates a II-VI Infrared optical component.
• This optical component contains a small amount of thorium fluoride, a type of source material (less
than 10% by weight).
•
It is exempt from USNRC licensing regulations as an "unimportant quantity of source material" per
10 CFR 40.13(c) (7).
•
Shaping, grinding, polishing, or alteration of the optical component is prohibited.
• Use of this optical component in contact lenses, spectacles, or in eyepieces in binoculars or other
similar optical instruments is prohibited.
Cleaning optical components is permitted so long as care is taken not to damage the coated surface of
the component as sold. This II-VI Infrared requirement only applies to lenses and optics manufactured and
distributed by II-VI Infrared. Distributing components or devices that contain lenses and optics
manufactured by other companies as if it were manufactured by II-VI Infrared is not in compliance with
USNRC distribution requirements.
U.S. distribution of components or devices that contain lenses and optics manufactured by other
companies which contain uranium and/or thorium requires a USNRC distribution license. Only II-VI Infrared
manufactured lenses and optics which contain thorium are covered by the II-VI Infrared distribution
license.
10 CFR 40.13(c) (7) Unimportant quantities of source material.
(7) Thorium or uranium contained in or on finished optical lenses and mirrors, provided that each lens or
mirror does not contain more than 10 percent by weight thorium or uranium or, for lenses manufactured
before August 27, 2013, 30 percent by weight of thorium; and that the exemption contained in this
paragraph does not authorize either:
(i) The shaping, grinding, or polishing of such lens or mirror or manufacturing processes other than the
assembly of such lens or mirror into optical systems and devices without any alteration of the lens or
mirror; or
(ii) The receipt, possession, use, or transfer of uranium or thorium contained in contact lenses, or in
spectacles, or in eyepieces in binoculars or other optical instruments.

Disposal

This product contains components that are considered hazardous industrial waste. If a situation occurs
where the laser is rendered non-functional and cannot be repaired, it may be returned to NOVANTA
