Note 1: Many radionuclides transform into other radionuclides.
In expressing the concentrations in Appendix A, the activity
stated is that of the parent radionuclide and takes into account
the radioactive decay products.
2-A-6
Note 2: Where there is involved a combination of radionuclides,
the limit for the combination should be derived as follows:
Determine for each radionuclide in the product the ratio between
the radioactivity concentration present in the product and the
exempt radioactivity concentration established in Appendix A for
the specific radionuclide when not in combination. The sum of
such ratios may not exceed "1".
Example: Concentration of Radionuclide A in Product +
Exempt concentration of Radionuclide A
Concentration of Radionuclide B in Product <1
Exempt concentration of Radionuclide B
Note 3: To convert µCi/ml to SI units of megabecquerels per liter
multiply
the above values by 37.

FOOTNOTES
1.
For
use
in
the
selection
of
respiratory
protective
equipment to be used only where the contaminants have been
identified
and
the
concentrations,
or
possible
concentrations, are known.
2.
Only for shaven faces and where nothing interferes with the
seal of tight-fitting facepieces against the skin. Hoods
and suits are excepted.
3.
The mode symbols are defined as follows:
CF = continuous flow
D = demand
NP = negative pressure, that is, negative phase during
inhalation
PD = pressure demand, that is, always positive pressure
PP = positive pressure
RD = demand, recirculating or closed circuit
RP = pressure demand, recirculating or closed circuit
4.
a.
The protection factor is a measure of the degree of
protection afforded by a respirator, defined as the
ratio of the concentration of airborne radioactive
material outside the respiratory protective equipment
to that inside the equipment, usually inside the
facepiece, under conditions of use. It is applied to
the ambient airborne concentration to estimate the
concentrations inhaled by the wearer according to the
following formula:
Concentration inhaled = Ambient airborne concentration
Protection factor
b.
The protection factors apply:
(i)
Only for individuals trained in using respirators
and wearing properly fitted respirators that are
used and maintained under supervision in a well-
planned respiratory protective program.
(ii) For air-purifying respirators only when high
efficiency particulate filters, above 99.97%
removal efficiency by thermally generated 0.3 Fm
dioctyl phthalate (DOP) test or equivalent, are
used in atmospheres not deficient in oxygen and
not
containing
radioactive
gas
or
vapor
respiratory hazards.
(iii)No adjustment is to be made for the use of
sorbents
against radioactive material in the form of
gases
or vapors.
(iv) For atmosphere-supplying respirators only when
supplied
with
adequate
respirable
air.
Respirable air shall be provided of the quality
and quantity required in accordance with the
National Institute for Occupational Safety and
Health
and
the
Mine
Safety
and
Health
Administration certification described in 30 CFR
11. Oxygen and air shall not be used in the same
apparatus.
4-A-3
5.
Excluding
radioactive
contaminants
that
present
an
absorption or submersion hazard. For tritium oxide,
approximately one-third of the intake occurs by absorption
through the skin so that an overall protection factor of
less than 2 is appropriate when atmosphere-supplying
respirators are used to protect against tritium oxide. If
the protection factor for respiratory protective equipment
is 5, the effective protection factor for tritium is about
1.4; with protection factors of 10, the effective factor
for tritium oxide is about 1.7; and with protection factors
of 100 or more, the effective factor for tritium oxide is
about 1.9. Air-purifying respirators are not suitable for
protection against tritium oxide. See also footnote 9
concerning supplied-air suits.
6.
Canisters and cartridges shall not be used beyond service-
life limitations.
7.
Under-chin type only. This type of respirator is not
satisfactory for use where it might be possible, such as,
if an accident or emergency were to occur, for the ambient
airborne concentrations to reach instantaneous values
greater than 10 times the pertinent values in Table I,
Column 3 of Appendix B of Subchapter 4. This type of
respirator is not suitable for protection against plutonium
or other high-toxicity materials. The mask is to be tested
for fit prior to use, each time it is donned.
8.
a.
Equipment shall be operated in a manner that ensures
that
proper
air
flow-rates
are
maintained.
A
protection factor of no more than 1000 may be utilized
for tested-and-certified supplied-air hoods when a
minimum air flow of 6 cubic feet per minute (0.17
m
3/min) is maintained and calibrated air line pressure
gauges or flow measuring devices are used. A
protection factor of up to 2000 may be used for tested
and certified hoods only when the air flow is
maintained at the manufacturer's recommended maximum
rate for the equipment, this rate is greater than 6
cubic feet per minute (0.17 m
3/min) and calibrated air
line pressure gauges or flow measuring devices are
used.
b.
The design of the supplied-air hood or helmet, with a
minimum flow of 6 cubic feet per minute (0.17 m
3/min)
of air, may determine its overall efficiency and the
protection it provides. For example, some hoods
aspirate contaminated air into the breathing zone when
the
wearer
works
with
hands-over-head.
This
aspiration may be overcome if a short cape-like
extension to the hood is worn under a coat or over-
alls. Other limitations specified by the approval
agency shall be considered before using a hood in
certain types of atmospheres. See footnote 9.
9.
Appropriate protection factors shall be determined, taking
into account the design of the suit and its permeability to
the contaminant under conditions of use. There shall be a
standby rescue person equipped with a respirator or other
apparatus
appropriate
for
the
potential
hazards
and
communications equipment whenever supplied-air suits are
used.
4-A-4
10.
No approval schedules are currently available for this
equipment. Equipment is to be evaluated by testing or on
the basis of reliable test information.
11.
This type of respirator may provide greater protection and
be used as an emergency device in unknown concentrations
for protection against inhalation hazards. External
radiation hazards and other limitations to permitted
exposure, such as skin absorption, must be taken into
account in such circumstances.
12.
Quantitative fit testing shall be performed on each
individual, and no more than 0.02% leakage is allowed with
this type of apparatus. Perceptible outward leakage of gas
from this or any positive pressure self-contained breathing
apparatus is unacceptable because service life will be
reduced substantially. Special training in the use of this
type of apparatus shall be provided to the wearer.
Note 1: Protection factors for respirators approved by the U.S.
Bureau of Mines and the National Institute for Occupational
Safety and Health, according to applicable approvals for
respirators for type and mode of use to protect against airborne
radionuclides, may be used to the extent that they do not exceed
the protection factors listed in this table. The protection
factors listed in this table may not be appropriate to
circumstances where chemical or other respiratory hazards exist
in addition to radioactive hazards. The selection and use of
respirators for such circumstances should take into account
applicable approvals of the U.S. Bureau of Mines and the
National Institute for Occupational Safety and Health.
Note 2: Radioactive contaminants, for which the concentration
values in Table I, Column 3 of Appendix B of Subchapter 4 are
based on internal dose due to inhalation, may present external
exposure
hazards
at
higher
concentrations.
Under
these
circumstances, limitations on occupancy may have to be governed
by external dose limits.

NOTE: Where there is involved a combination of radionuclides in known
amounts, the limit for the combination shall be derived as follows:
determine, for each radionuclide in the combination, the ratio between the
quantity present in the combination and the limit otherwise established for
the specific radionuclide when not in combination. The sum of such ratios for
all radionuclides in the combination may not exceed "1" -- that is, unity.
1The quantities listed above were derived by taking 1/10th of the most
restrictive ALI listed in Table I, Columns 1 and 2, of Appendix B to
Subchapter 4, rounding to the nearest factor of 10, and constraining the
values listed between 37 Bq and 37 MBq (0.001 and 1,000 FCi). Values of 3.7
MBq (100 FCi) have been assigned for radionuclides having a radioactive half-
life in excess of E+9 years, except rhenium, 37 MBq (1,000 FCi), to take into
account their low specific activity.
* To convert FCi to kBq, multiply the FCi value by 37.

Maximum design workload for the facility including
total weekly radiation output, expressed in gray (rad)
or air kerma at one meter, total beam-on time per day
or week, the average treatment time per patient, along
with the anticipated number of patients to be treated
per day or week.
C.
A facility blueprint/drawing indicating: scale 0.25
inch = one foot is typical; direction of North; normal
location of the therapeutic radiation machine's
radiation port(s); the port's travel and traverse
limits; general direction(s) of the useful beam;
locations of any windows and doors; and the location
of the therapeutic radiation machine control panel.
If the control panel is located inside the external
beam radiation therapy treatment room, the location of
the operator's booth shall be noted on the plan and
the operator's station at the control panel shall be
behind a protective barrier sufficient to ensure
compliance with subchapter 4.
D.
The structural composition and thickness or
lead/concrete equivalent of all walls, doors,
partitions, floor, and ceiling of the room(s)
concerned.
E.
The type of occupancy of all adjacent areas inclusive
of space above and below the room(s) concerned. If
there is an exterior wall, show distance to the
closest area(s) where it is likely that individuals
may be present.
F.
At least one example calculation which shows the
methodology used to determine the amount of shielding
14-A-2
required for each physical condition (ie: primary and
secondary/leakage barriers, restricted and
unrestricted areas, entry door(s)) and shielding
material in the facility.
(1)
If commercial software is used to generate
shielding requirements, please also identify the
software used and the version/ revision date.
(2)
If the software used to generate shielding
requirements is not in the open literature,
please also submit quality control sample
calculations to verify the result obtained with
the software.

photons with a maximum energy in excess of one hundred fifty
kV and/or electrons and/or protons or other subatomic
particles shall submit shielding plans which contain, as a
minimum, the following additional information:
A.
Equipment specifications including the manufacturer
and model number of the therapeutic radiation machine,
and gray (rad) at the isocenter and the energy(s) and
type(s) of radiation produced (ie: photon, electron).
The source to isocenter distance shall be specified.
B.
Maximum design workload for the facility including
total weekly radiation output expressed in gray (rad)
at one meter, total beam-on time per day or week, the
average treatment time per patient, along with the
anticipated number of patients to be treated per day
or week.
C.

work-load, presence of integral beam-stop in unit,
occupancy and use(s) of adjacent areas, fraction of
time that useful beam will intercept each permanent
barrier (walls, floor and ceiling) and "allowed"
radiation exposure in both restricted and unrestricted
areas.
