ITEMS CONTAINING BYPRODUCT MATERIAL--Table of Contents
 
                   Subpart B--Generally Licensed Items
 
Sec. 32.102  Schedule C--prototype tests for calibration or reference 
sources containing americium-241.

    An applicant for a license pursuant to Sec. 32.57 shall, for any 
type of source which is designed to contain more than 0.005 microcurie 
of americium-241, conduct prototype tests, in the order listed, on each 
of five prototypes of such source, which contains more than 0.005 
microcurie of americium-241, as follows:
    (a) Initial measurement. The quantity of radioactive material 
deposited on the source shall be measured by direct counting of the 
source.
    (b) Dry wipe test. The entire radioactive surface of the source 
shall be wiped with filter paper with the application of moderate finger 
pressure. Removal of radioactive material from the source shall be 
determined by measuring the radioactivity on the filter paper or by 
direct measurement of the radioactivity on the source following the dry 
wipe.
    (c) Wet wipe test. The entire radioactive surface of the source 
shall be wiped with filter paper, moistened with water, with the 
application of moderate finger pressure. Removal of radioactive material 
from the source shall be determined by measuring the radioactivity on 
the filter paper after it has dried or by direct measurement of the 
radioactivity on the source following the wet wipe.
    (d) Water soak test. The source shall be immersed in water at room 
temperature for a period of 24 consecutive hours. The source shall then 
be removed from the water. Removal of radioactive material from the 
source shall be determined by direct measurement of the radioactivity on 
the source

[[Page 539]]

after it has dried or by measuring the radioactivity in the residue 
obtained by evaporation of the water in which the source was immersed.
    (e) Dry wipe test. On completion of the preceding test in this 
section, the dry wipe test described in paragraph (b) of this section 
shall be repeated.
    (f) Observations. Removal of more than 0.005 microcurie of 
radioactivity in any test prescribed by this section shall be cause for 
rejection of the source design. Results of prototype tests submitted to 
the Commission shall be given in terms of radioactivity in microcuries 
and percent of removal from the total amount of radioactive material 
deposited on the source.
