Nevada Administrative Code › Chapter 459 - Hazardous Materials › RADIATION CONTROL › Standards for Protection Against Radiation › Section 459.320 - Purpose; applicability; reasonable effort required

Current
				  through June 11, 2024
1.
				  The provisions of NAC 459.320 to 459.374, inclusive, establish standards for
				  protection against radiation hazards. It is the purpose of those sections to
				  control the receipt, possession, use, disposal and transfer of licensed or
				  registered sources of radiation by any licensee or registrant in such a manner
				  that the total dose to a natural person, including exposures to licensed or
				  unlicensed or registered or unregistered sources of radiation, whether in the
				  possession of the licensee, registrant or any other person, but not including
				  exposure to radiation from natural background sources, medical diagnosis and
				  therapy, natural persons who have been administered radioactive drugs or have
				  received permanent implants containing radioactive material and have been
				  released from the control of a licensee pursuant to
				  10
				  C.F.R. §
										35.75, or voluntary
				  participation in medical research does not exceed the standards of radiation
				  protection set forth in NAC 459.320 to 459.374, inclusive. Those sections will
				  not be construed as limiting actions that may be necessary to protect the
				  health and safety of the public.
2.
				  Except as otherwise specifically provided, NAC 459.320 to 459.374, inclusive,
				  apply to all licensees or registrants. Those sections do not limit the
				  intentional exposure of natural persons to radiation for the purpose of medical
				  use or the intentional exposure of natural persons to radiation who are
				  voluntarily participating in programs for medical research.
3. In addition to complying with the
				  requirements set forth in NAC 459.320 to 459.374, inclusive, a licensee or
				  registrant shall make every reasonable effort to maintain exposures and
				  releases of radioactive materials in effluents to unrestricted areas, as low as
				  is reasonably achievable.

Nevada Administrative Code › Chapter 459 - Hazardous Materials › RADIATION CONTROL › Standards for Protection Against Radiation › Section 459.323 - Weighting factors

Current through June 11,

1. For calculating
				  the effective dose equivalent, the values of the weighting factor are as
				  follows:
Organ Dose Weighting
				  Factors

2. For the purposes of weighting the
				  remainder dose, 0.30 results from 0.06 of each of five remainder organs,
				  excluding the skin and the lens of the eye, that receive the highest
				  doses.

				  as follows:
Quality Factors and
				  Absorbed Dose Equivalencies

				  per hour, as provided in subsection 1, 1 rem of neutron radiation of unknown
				  energies may, for the purposes of NAC 459.010 to 459.950, inclusive, be assumed
				  to result from a total fluence of 25,000,000 neutrons per square centimeter
				  incident upon the body. If sufficient information exists to estimate the
				  approximate energy distribution of the neutrons, the licensee or registrant may
				  use the fluence rate per unit dose equivalent or the appropriate quality factor
				  value from the following table to convert a measured tissue dose in rads to
				  dose equivalent in rem:

Nevada Administrative Code › Chapter 459 - Hazardous Materials › RADIATION CONTROL › Standards for Protection Against Radiation › Section 459.325 - Limits on occupational doses for adults

Current through June 11,
				  2024
1. Except as
				  otherwise provided in subsection 5, a licensee or registrant shall control
				  occupational doses, except for planned special exposures, to ensure that no
				  adult receives annually occupational doses in excess of the following limits:
(a) The lesser of:
(1) A total effective dose equivalent of 5
				  rems (50 millisieverts); or
(2) The
				  sum of the deep-dose equivalent and the committed dose equivalent to any
				  individual organ or tissue, other than the lens of the eye, of 50 rems (500
				  millisieverts);
Nevada Administrative Code › Chapter 459 - Hazardous Materials › RADIATION CONTROL › Standards for Protection Against Radiation › Section 459.3255 - Compliance with requirements for summation of external and internal doses

Current through June 11, 2024
1. If a licensee is required to monitor a
				  person pursuant to subsections 1 and 2 of NAC 459.339, the licensee shall
				  demonstrate compliance with the limits set forth in NAC 459.325 by adding
				  external and internal doses. The licensee may demonstrate compliance with the
				  requirements for summation of external and internal doses by meeting one of the
				  conditions specified in subsection 2 and the conditions specified in
				  subsections 3 and 4. The lens dose equivalent and the dose equivalents for the
				  skin and the extremities are not required to be included in the summation, but
				  are subject to separate limits set forth in NAC 459.325. If a licensee or
				  registrant is required to monitor a person pursuant to subsection 1 of NAC
				  459.339 only or pursuant to subsection 2 of NAC 459.339 only, the summation of
				  the doses is not required.
2. If
				  the only intake of radionuclides is by inhalation, the limit for the total
				  effective dose equivalent is not exceeded if the deep-dose equivalent divided
				  by the limit for the total effective dose equivalent, and one of the following,
				  does not exceed unity:
(a) The sum of the
				  fractions of the annual limit on intake by inhalation for each
				  radionuclide.
(b) The total number
				  of derived air concentration-hours for all radionuclides, divided by
				  2,000.
(c) The sum of the committed
				  effective dose equivalents to all significantly irradiated organs or tissues,
				  calculated from bioassay data using appropriate biological models and expressed
				  as a fraction of the annual limit. For the purposes of this subsection, an
				  organ or tissue shall be deemed to be irradiated significantly if, for that
				  organ or tissue, the product of the weighting factors and the committed dose
				  equivalent, per unit intake, is greater than 10 percent of the maximum weighted
				  value of the committed dose equivalent, per unit intake for any organ or
				  tissue.
Nevada Administrative Code › Chapter 459 - Hazardous Materials › RADIATION CONTROL › Standards for Protection Against Radiation › Section 459.327 - Determination of external dose from airborne radioactive material

Current through June 11, 2024
1. Licensees shall, when determining the
				  external dose from airborne radioactive material, include the deep-dose
				  equivalent, lens dose equivalent and shallow-dose equivalent caused by external
				  exposure to the cloud of airborne radioactive material.
2. Measurements of airborne radioactive
				  material and derived air concentration must not be used as the primary means to
				  assess the deep-dose equivalent if the airborne radioactive material includes
				  radionuclides other than noble gases or if the cloud of airborne radioactive
				  material is not relatively uniform. The determination of the deep-dose
				  equivalent must be based upon measurements using instruments or personnel
				  monitoring equipment.

A licensee or registrant may permit a worker
				  who is an adult to receive a planned special exposure, in addition to and

				  before the planned special exposure is scheduled to occur, and verifies that
				  the Division has received the letter of notification.
2. The planned special exposure is to occur
				  in an exceptional situation when alternatives that might avoid the higher
				  exposure are unavailable or impractical.
3. The licensee or registrant, and employer
				  if the employer is not the licensee or registrant, specifically authorizes the
				  planned special exposure, in writing, before the exposure occurs.
