Fla. Admin. Code Ann. R. 64E-5.615 - Use, Calibration and Check of Survey Instruments
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.
