ECD licenses
Customers in the United states can purchase a uECD under
either a General License or a Specific License. Customers
outside the United States should contact their local Agilent
sales office for information.
Specific License Specific License uECDs require you to obtain
a Materials License from the Nuclear Regulatory Commission
(NRC) or the local state agency, permitting you to possess the
amount and kind of radioisotope used in the detector. You can
typically ship, sell, or transfer the ECD to other Specific
Licensees. If the license permits, you may also open the uECD
for cleaning.
General License General License uECDs do not require a
Materials License. You become a General Licensee automatically
when you purchase a uECD directly from Agilent Technologies.
Some states may require that you register the uECD with a state
agency.
Certain restrictions apply to General Licenses:
1 Owners may not open the uECD cell.
2 Owners shall not modify the cell in any manner.
3 Owners shall not use any solvent, including water, to
internally clean the cell.
4 Owners shall not interfere with or attempt to defeat the
overheat circuitry that may be supplied with the uECD.
5 Owners shall not transfer the uECD to another person or
another location except as described in the applicable
Regulations.
6 Owners must perform a radioactive leak test at least every
6 months.
7 Owners must maintain records as required by your local
Agency (the NRC or, in certain states, a state agency).
8 Owners must notify the Agency in case of incidents or
failures that might lead to a hazardous condition.
Additional information is available in the publication
“Information for General Licensees,” part no. 5961- 5664.
uECD warnings
Although beta particles at this energy level have little
penetrating power —the surface layer of the skin or a few sheets
of paper will stop most of them—they may be hazardous if the
