MDA CALCULATION

The minimum detectable counting rate (MDR) is given by:

MDR = p * counts
T

where:
• p = precision (the precision can range from 1 to 9 – the default value is 3),
• counts = the sum of the total background counts in all relevant channels (ROI) for the
selected nuclide multiplied by the counting time (in minutes for Ci; in seconds for Bq)
• T = counting time (in minutes for Ci; in seconds for Bq).

To obtain the Minimum Detectable Activity, the minimum detectable counting rate (MDR) is
multiplied by the Conversion Factor for the nuclide:

MDA = MDR × cf

where:
• cf = Conversion Factor of the selected nuclide

Note: The selected nuclide’s Conversion Factor used in the calculation can be found by
printing the diagnostics or by viewing it from the Setup Menu as described in
CHAPTER 6: CONVERSION FACTORS FOR NUCLIDES.

Example Calculations
1.) Example calculation using the values in Figure 16-8 MDA Test Results (Curie)
Printout:

Selected nuclide = Tc99m
cf = 1.40 (Tc99m Conversion Factor)
p=3
counts = 98.7 (Tc99m ROI channel 1 counts) + 101.0 (Tc99m ROI channel 2 counts)
T = 3 minutes (180 seconds)

MDR = 3× (98.7 +101.0)× 3 = 3× 199.7 × 3 = 3× 599.1 = 3× 24.477 = 24.477

CHAPTER 17

N.R.C. REGULATIONS AND
GUIDELINES FOR AREA SURVEY

MONITORING (WIPE TESTING)

The U.S. Nuclear Regulatory Commission (N.R.C) publishes regulatory guidelines for
medical uses of radioactive materials. The following guidelines were taken from the N.R.C
website, www.nrc.gov, from the N.R.C.’s Regulatory Guide 10.8, Guide for the Preparation of
Applications for Medical Use Programs (Revision, 2 August 1987).

The following pages describe Model Procedures for: Leak-Testing Sealed Sources, Safely
Opening Packages Containing Radioactive Material and Area Surveys. For more information,
contact your radiation safety officer, state regulatory agency for radiation safety or the N.R.C.

APPENDIX H: Model Procedure for Leak-Testing Sealed Sources

(See § 35.59.)

You or your contractor may use the following model procedure to leak-test sealed sources. If
you, or the contractor, follow the model procedure you may say on your application, "We will
establish and implement the model procedure for leak-testing sealed sources that was
published in Appendix H to Regulatory Guide 10.8, Revision 2."

You may develop your own procedure for review. If you do so, you should consider for
inclusion all the features in the model and carefully review the requirements of § 35.59. Say
on your application, "We have developed a leak-test procedure for your review that is
appended as ATT 10.3," and append your leak-test procedure.

Model Procedure

1. Make a list of all sources to be tested. This should include at least the isotope, the activity on a
specified date, and the physical form.

2. If you will be testing sources stronger than a few millicuries, set out a survey meter, preferably with
a speaker, so you can monitor your exposure rate.

3. Prepare a separate wipe sample for each source. A cotton swab, injection prep pad, filter paper, or
tissue paper is suitable. Number each wipe so you will know for which source it is to be used.
Samples should be taken as follows:
a. For small sealed sources, it may be easier to wipe the entire accessible surface area. Pay
particular attention to seams and joints. However, do not wipe the port of beta applicators.
b. For larger sealed sources and devices (survey meter calibrator, bone mineral analyzer source),
take the wipe near the radiation port and on the activating mechanism.
c. For teletherapy machines, take the wipe with the source in the off position. Wipe the area near
the shutter mechanism, taking care to touch neither field light and mirror nor crosshairs. Also wipe

September 07 N.R.C. REGULATIONS & GUIDELINES 17 - 1

CAPINTEC, INC. CAPRAC®-R

the primary and secondary collimators and trimmers.

d. If you are testing radium sources at the same time you are testing NRC-licensed sources, they
should also be checked for radon leakage. This can be done by submerging the source in a vial
of fine-grained charcoal or cotton for a day. Then remove the source and analyze the adsorbent
sample as described below. A survey should be done to be sure the sources are adequately
shielded during the leak-test period.

4. The samples will be analyzed as follows:

a. Select an instrument that is sufficiently sensitive to detect 0.005 microcurie. For beta sources, a
proportional flow counter, liquid scintillation counter, or thin-end-window GM survey meter may be
appropriate. For gamma sources, a crystal with a ratemeter or scaler or a GM survey meter may
be appropriate. Dose calibrators used in nuclear medicine are not sufficiently sensitive.

b. To estimate the detection efficiency of the analyzer used to assay the wipe samples, assay a
check source that has the same isotope as the sealed source and whose activity is certified by
the supplier. If one is not available, it will be necessary to use a certified check source with a
different isotope that has a similar spectrum. If calculations demonstrate that the instrument is not
sufficiently sensitive to detect 0.005 microcurie, a different instrument must be used.

c. Assay the wipe sample. It must be in the same geometry relative to the detector as was the
certified check source.

d. Record the wipe sample counts per minute. Then calculate and record the estimated activity in
microcuries on the wipe sample.

e. Continue the same analysis procedure for all wipe samples.

f. If the wipe sample activity is 0.005 microcurie or greater, notify the RSO. The source must be
withdrawn from use to be repaired or discarded. If it is a source distributed under an NRC or
Agreement State license, the NRC must be notified. (See paragraph 21.21(b) of 10 CFR Part 21
and paragraph 35.59(e)(2) of 10 CFR Part 35.)

g. Sign and date the list of sources, data, and calculations.

APPENDIX L: Model Procedure for Safely Opening Packages Containing
Radioactive Material

(See §§ 35.23, 30.51, 20.203(f)(4), and 20.205.)

You may use the following model procedure for opening packages. If you follow the model
procedure, you may say on your application, "We will establish and implement the model
procedure for opening packages that was published in Appendix L to Regulatory Guide 10.8,
Revision 2."

If you develop your own package opening procedure for review, you should consider for
inclusion all the features in the model. Say on your application, "We have developed a
package opening procedure for your review that is appended as ATT 10.7," and append your
package opening procedure.

17 - 2 N.R.C. REGULATIONS & GUIDELINES September 07

CAPINTEC, INC. CAPRAC®-R

Model Procedure

1. Special requirements must be followed for packages containing quantities of radioactive material in
excess of the Type A quantity limits specified in paragraph 20.205(b) of 10 CFR Part 20 (e.g., more
than 20 curies of Mo-99, Tc-99m, uncompressed Xe-133, or more than 3 curies of Xe-133, I-131,
Cs-137, Ir-192, I-125, or more than 0.001 curie of Ra-226). Such packages must be monitored for
external radiation levels and surface contamination within 3 hours after receipt if received during
working hours or within 18 hours if received after working hours, in accordance with the
requirements of paragraphs 20.205(a) through (c). The NRC Regional Office must be notified if
removable contamination exceeds 0.01 microcurie (22,000 dpm)/100 cm*.

2. For packages received under the specific license, the following procedure for opening each package
will be followed:

a. Put on gloves to prevent hand contamination.

b. Visually inspect the package for any sign of damage (e.g., wet or crushed). If damage is noted,
stop the procedure and notify the Radiation Safety Officer (RSO).

c. Measure the exposure rate from the package at 1 meter and at the package surface. If it is
higher than expected, stop and notify the RSO. (The "transport index" noted on packages with
"Yellow II" or "Yellow III" labels is the approximate dose rate, in millirem per hour, at 1 meter from
the package surface (see § 71.4 of 10 CFR Part 71); the surface dose rate for such packages
should not exceed 200 millirem per hour. The dose rate from packages with "White I" labels
should be less than 0.5 millirem per hour at the package surface. (See § 172.403 of 49 CFR Part
172.))

d. Open the package with the following precautionary steps:

(1) Remove the packing slip.

(2) Open the outer package following the supplier's instructions, if provided.

(3) Open the inner package and verify that the contents agree with the packing slip.

(4) Check the integrity of the final source container. Look for broken seals or vials, loss of liquid,
condensation, or discoloration of the packing material.

(5) If anything is other than expected, stop and notify the RSO.

e. If there is any reason to suspect contamination, wipe the external surface of the final source
container and remove the wipe sample to a low-background area. Assay the wipe sample to
determine if there is any removable radioactivity. [The licensee should specify in the procedure
manual which instrument, for example, a thin-end-window GM survey meter, a NaI(Tl) crystal
and ratemeter, a liquid scintillation counter, or a proportional flow counter, should be used for
these assays. The detection efficiency must be determined to convert wipe sample counts per
minute to disintegrations per minute. Note that a dose calibrator is not sufficiently sensitive for
this measurement.] Take precautions against the potential spread of contamination.

f. Check the user request to ensure that the material received is the material that was ordered.

g. Monitor the packing material and the empty packages for contamination with a radiation
detection survey meter before discarding.

(1) If contaminated, treat this material as radioactive waste.

(2) If not contaminated, remove or obliterate the radiation labels before discarding in in-house
trash.

h. Make a record of the receipt.

3. For packages received under the general license in § 31.11, the following procedure for opening
each package will be followed:

a. Visually inspect the package for any sign of damage (e.g., wet or crushed). If damage is noted,
stop the procedure and notify the RSO.

b. Check to ensure that the material received is the material that was ordered.

See Exhibit 12 for a sample record form you may want to use.

APPENDIX N: Model Procedure for Area Surveys

(See § 35.70.)

You may use the following model procedure to perform area surveys. If you follow the model
procedure, you may say on your application, "We will establish and implement the model
procedure for area surveys that was published in Appendix N to Regulatory Guide 10.8,
Revision 2."

You may develop your own procedure for review. If you do so, you should consider for
inclusion all the features in the model procedure and carefully review the requirements of
§35.70. Say on your application, "We have developed survey procedures for your review that
are appended as ATT 10.12," and append your survey procedures.

Model Procedure

Ambient Dose Rate Surveys

1. Survey Areas
a. In radiopharmaceutical elution, preparation, and administration areas, survey at the end of each
day of use with a radiation detection survey meter. If diagnostic administrations are occasionally
made in patients' rooms and special care is taken to remove all paraphernalia, those rooms need
not be surveyed.
b. In laboratory areas where only small quantities of gamma-emitting radioactive material are
processed (less than 200 microcuries at a time), survey monthly with a radiation detection survey
meter.
c. In radiopharmaceutical storage and radiopharmaceutical waste storage areas, survey weekly with
a radiation detection survey meter.
d. In sealed source and brachytherapy storage areas, survey quarterly with a radiation
measurement survey meter.

2. Immediately notify the RSO if you find unexpectedly high or low levels.

Removable Contamination Surveys

1. Survey Areas
a. In radiopharmaceutical elution, preparation, and administration areas, survey weekly for
removable contamination. If diagnostic administrations are occasionally made in patients' rooms
and special care is taken to remove all paraphernalia, those rooms need not be surveyed.
b. In laboratory areas where only small quantities of photon-emitting radioactive material are
processed (less than 200 microcuries at a time), survey monthly for removable contamination.
c. In radiopharmaceutical storage and radiopharmaceutical waste storage areas, survey weekly for
removable contamination.

2. The wipe sample assay procedure should be sufficiently sensitive to detect the presence of 2000
dpm/100 cm* of removable contamination (200 dpm/100 cm* for isotopes of iodine). You must use a
radioactive source with a known amount of activity to convert sample measurements (usually in
counts per minute or cpm) to disintegrations per minute or dpm.

3. Immediately notify the RSO if you find unexpectedly high levels.
