Kan. Admin. Regs. § 28-35-135h - Definitions
As used in these regulations, each of the following terms shall have the meaning assigned in this regulation:
(a) "Half-life" means the time required for
the activity of any given radioisotope to decay to one-half of its original
activity.
(b) "Half-value layer
(HVL)" means the thickness of specified material that attenuates the beam of
radiation to an extent that the exposure rate is reduced to one-half of its
original value.
(c) "Hands-on
experience," as applied to industrial radiology, means experience in all areas
considered to be directly involved in the radiography process. This term shall
include taking radiographs, the calibration of survey instruments, operational
and performance testing of survey instruments and devices, film development,
the posting of radiation areas, transporting radiography equipment, the posting
of records and radiation area surveillance, and other areas as applicable. A
disproportionate amount of time spent in only one or two of these areas shall
not be counted toward the 2,000 hours of hands-on experience required for a
radiation safety officer or a radiographer.
(d) "Hazardous waste" shall have the meaning
assigned in K.A.R. 28-31-3.
(e)
"Healing arts" means the activities authorized in
K.S.A. 65-2801 et seq., and amendments thereto.
(f) "Healing arts screening" means
the testing of human beings using X-ray machines for the detection or
evaluation of health indications when the test is performed without any prior
examination and without any specific and individual order by a licensed
practitioner of the healing arts who is legally authorized to perform
examinations and to prescribe X-ray tests for the purpose of diagnosis or
treatment.
(g) "Heat unit" means a
unit of energy equal to the product of the peak kilovoltage, milliamperes, and
seconds (kVp * mA * second).
(h)
"High dose-rate remote afterloader" means a brachytherapy device that remotely
delivers a dose rate in excess of 12 grays (1,200 rads) per hour at the point
or surface where the dose is prescribed.
(i) "High-radiation area" means any area that
is accessible to individuals, in which there exists radiation at such levels
that a major portion of the body could receive, in any one hour and at 30
centimeters from the source of the radiation or any surface that the radiation
penetrates, a dose to the whole body in excess of 100 millirems. For purposes
of these regulations, rooms or areas in which diagnostic X-ray systems are used
for healing arts purposes shall not be considered high-radiation areas.
(j) "Human use" means the
intentional internal or external administration of radiation or radioactive
material to any individual.
