A licensee shall ensure that the survey instruments used to
comply with this part have been calibrated before first use, at least every 12
months, and after repair.
(1) A record
shall be made of each calibration, which shall include:
(a) A description of the source
used;
(b) The certified dose rates
from the source;
(c) The rates
indicated by the instrument being calibrated;
(d) The correction factors deduced from the
calibration data;
(e) The name of
the individual who performed the calibration;
(f) The date of calibration;
(g) The model number and serial number of the
instrument being calibrated; and,
(h) The results of the
calibration.
(2) The
licensee shall:
(a) Calibrate all required
scale readings up to 1, 000 millirems (10 mSv) per hour with a radiation
source;
(b) Calibrate each linear
scale instrument at two points located approximately 1/3 and 2/3 of full-scale,
calibrate each logarithmic scale instrument at midrange of each decade and at
two points of at least one decade, and calibrate each digital instrument at
appropriate points; and,
(c)
Conspicuously note on the instrument the date of
calibration.
(3) The
licensee shall:
(a) Consider a point as
calibrated if the indicated dose rate differs from the calculated dose rate by
not more than 10 percent; and,
(b)
Consider a point as calibrated if the indicated dose rate differs from the
calculated dose rate by not more than 20 percent and a correction chart or
graph is attached conspicuously to the instrument.
(4) A licensee shall check each survey
instrument for proper operation with a dedicated check source before each use.
The licensee is not required to keep records of these checks.
(5) The licensee shall retain a record of
each calibration required in subsection
64E-5.615(1),
F.A.C., for 3 years.
(6) The
licensee may use persons licensed by the department, the U.S. Nuclear
Regulatory Commission, an agreement state, or a licensing state to perform
calibrations of survey instruments. Records of calibrations required by
subsection
64E-5.615(1),
F.A.C., shall be maintained by the licensee.
(7) A licensee authorized to use radioactive
material for uptake, dilution, and excretion studies or sealed sources for
diagnostic purposes shall possess a portable radiation survey instrument with a
range from 0.1 millirem (1.0 µSv) per hour to at least 1, 000 millirem
(10 mSv) per hour.
(8) A licensee
authorized to use radioactive material for imaging and localization studies,
radiopharmaceutical therapy or implant therapy shall possess portable radiation
survey instruments with a range from 0.1 millirem (1.0 µSv) per hour to
at least 1, 000 millirem (10 mSv) per hour.
(9) A licensee authorized to use radioactive
material in Rule
64E-5.634, F.A.C., shall possess
a radiation survey instrument as described in subsection (7) or (8),
above.
(10) The licensee shall not
use survey instruments if the difference between the indicated exposure rate
and the calculated exposure rate is more than 20 percent.
(11) A licensee may calibrate instrumentation
used in Rule
64E-5.615, F.A.C., using
nationally recognized standards or the manufacturer's instructions. The
standards or instructions used by the licensee must be available for inspection
by the department.
