AMEN DMENT N UMBER
107
The licensee is authorized to store radioactive material with a physical half-life of less than 270 days for
decay-in-storage before being discarded as being non-radioactive provided:
A. Radioactive waste to be discarded of in this manner is held for decay a minimum of 10 half-lives.
B. Prior to discarding as other waste, radioactive waste is monitored to determine that the radiation levels
are not distinguishable from background with appropriate survey instruments. All radiation labels will
be removed or otherwise obliterated or obscured.
C. Generator columns shall be segregated so that they may be monitored separately to assure decay to
background levels prior to discarding.
19.
The licensee shall test each device distributed under this license for leakage or contamination of radioactive
material and proper operation of the "on-off" mechanism and indicator, if any, at the time of installation of
the device.
20.
After installation by the licensee of each device distributed to persons generally licensed pursuant to
25 TAC §289.251(f), the licensee shall conduct a radiation survey and shall assure that the levels of
radiation do not exceed those specified in the license authorizing the manufacture or distribution of the
installed gauge. The licensee shall furnish the general licensee a copy of the radiation survey report.
21.
The licensee is hereby authorized to perform commercial radiation survey instrument calibration.
22.
The licensee shall possess and use sealed sources authorized in Part A of Conditions 5, 6 , 7 and 8 only
after acquiring documentation from the manufacturer that a safety evaluation require<! by 25 T AC
§289.252(v) has been performed. This documentation shall be maintained for inspection by the Agency.
23.
Each device distributed under this license shall be accompanied by at least the following or substantially
similar statements:
A. Persons who receive , use, or transfer this device are subject to a general license pursuant to these
rules, or equivalent regulations of the NRC or another Agreement State.
B. Abandonment or disposal of the device is prohibited unless it is transferred to a person specifically
licensed by the Agency, the NRC, or another Agreement State.
C . Operation of this device is prohibited if there is failure of or damage to the shielding, source
containment, or "on-off" mechanism.
D. Dismantling, maintenance, and testing of the radioactive material shielding or containment shall be
performed only by persons specifically licensed by the Agency, the NRC, or another Agreement State.
E. This device shall be tested for radioactive leakage at intervals not to exceed six months.
F. Loss, theft, or transfer of this device and failure or damage to the shielding, or source containment
shall be reported to the Agency, the NRC, or the appropriate Agreement State.
G. Removal of any label from this device is prohibited.
H . This device shall be tested for proper operation of the "on-off" mechanism and indicator at intervals
not to exceed six months.
24.
When using radioactive material authorized in Part AG, the licensee shall determine through calculation
and post the high radiation area in accordance with 25 TAC §289.202(aa).

The licensee is hereby authorized to perform smoke detector Am-241 foil recovery operations and assembly
into plastic disc sources for in-house use only in accordance with letters dated February 20, 2010 and May
29, 2010. In addition to the commitments, representations and statements contained in the afore-mentioned
letters, when conducting smoke detector Am-241 foil recovery and assembly of plastic disc sources, the
licensee shall:
A . conduct contamination surveys of the Am-241 foil source chamber (cage) prior to recovery by wiping
the source chamber (cage) using a disposable paper towel or other absorbent material and counting the
sample using a low energy scintillation probe or thin-end window GM tube.
B. not attempt to recover a Am-241 foil source suspected of leaking or encased in a contaminated
chamber.
C . recover only Am-241 foil sources having an activity not exceeding 1.0 ~Ci.
D . maintain direct observation of all new plastic discs containing radioactive material during all phases of
assembly until newly assembled plastic sources are placed in storage.
E. dispose of leaking Am-241 foil sources, associated contaminated items and contaminated absorbent
work space coverings as radioactive waste.
F . document all contamination surveys required by the afore-mentioned letters and as directed by this
license condition. Contamination survey records shall include, as a minimum, the name of the person
conducting contamination surveys and records the results, date, unique id number of chamber and/or
in-house control number, survey results , and disposition of leaking sources.
G. label newly assembled in-house plastic discs per 25 TAC §289.202(cc) such that, as a minimum, the
label includes the words "Caution Radioactive Material," estimate of quantity of radioactive material
and the in-house control number.
26.
When using radioactive material authorized in Part AL , the licensee shall only use the NUMEC device
with the source in the central storage position and experiment wells, when not in use, containing neutron
moderating material.
27.
This license does not authorize the distribution of exempt quantities of byproduct or source material.
28.
The licensee is hereby authorized to perform calibration, service and repair of radiation detection
instruments with incidental fixed radioactive contamination for specifically licensed nuclear service
providers and nuclear power plant customers. Areas where such instruments are received, used and stored
must be monitored for the presence of radioactive contamination as indicated below:
A. Survey all areas where radiation detection instruments with fixed contamination are received ,
calibrated, serviced, repaired and prepared for shipment following each day of use;
B. Survey all areas where radiation detection instruments with fixed contamination are stored at the
conclusion of each week of use;
C. Monitor for removable contamination all areas where radiation detection instruments with fixed
contamination are received, stored, calibrated, serviced, repaired and prepared for shipment at the
conclusion of each week of use; and
D. The licensee shall compare survey and removable contamination analysis results with established action
levels that are no less restrictive than 25 T AC §289. 202(ggg)(6). The licensee shall make
arrangements for decontamination of all areas that exceed the licensee's established action levels.
