7、ss. 5.3.2 Filled Phantom The material used to fill the phantom shall meet the criteria specified in Section 4.2 of this standard. The uncertainty in the density of the filler material should be measured by a quantitative process (such as weighing the phantom). Visual inspection shall not be used in

8、place of quantitative testing, but shall be used only to check for gross defects. Aqueous solutions shall maintain all chemical species in solution and inhibit plate-out of material on the walls of the phantom shell. The solution chemistry shall prevent precipitation of the radioactive material and

9、other additives. The shells shall be leak-tested and found to have no measurable leakage. If a phantom is stored for a prolonged period of time, measures shall be taken to minimize biological growths in the phantom to preclude changes in chemical species and the activity distribution. 5.3.3 Radioact

10、ive Material Content The quantity of radioactive material incorporated in the phantom and the associated uncertainties shall be determined and documented in writing for each section of the phantom and for the total phantom. The total uncertainty shall include the uncertainties in the standard refere

11、nce material, dilution procedures, gravimetric analysis, counting errors, and other errors as appropriate. The calculations used to determine the final quantity of radioactive material added to the phantom shall be reviewed and approved by a qualified person other than the person who did the origina

12、l calculations. The review and approval shall be documented in writing. The radioactive material contained in each section shall be homogeneously distributed throughout the volume of each section. The tolerance for the variability of the activity distribution shall be less than 10%. The variability

13、of the activity distribution in the material used to fill the phantom shall be determined quantitatively at least once to evaluate the adequacy of the mixing method. The radioactive material content of the phantom shall be traceable to the National Institute of Standards and Technology (NIST) unless

14、 it is not required for the application. Procedures for the preparation of radioactive material standards shall be documented in writing. 5.3.4 Records The records related to each BOMAB phantom shall include the following as a minimum: material composition and density of the shell and filler matrix

15、materials; shell wall thickness and estimate of variability in the thickness; values for height and diameters with associated tolerances for each section and the total phantom; ANSI/HPS N13.35-2009 5 volumes and associated tolerances for the individual sections and the total phantom; photon interact

16、ion properties of the phantom shell and fill materials over the energy range of interest (needs to be done only once, if the density is measured and remains constant); calculations of totalactivityandassociateduncertainty for the radionuclide(s) in each section and total phantom; variability in the

17、distribution of radioactive material; NIST calibration certificate, or equivalent, for the radioactive standards incorporated in the phantom; results from leakage tests of shell. Records shall be retained in accordance with applicable standards including ANSI/HPS N13.6. 6.0 References 6.1 Normative

27、 (Normative) Data for BOMAB Phantoms of Different Sizes Due to the range of heights and weights of workers, it is necessary to have various sizes of BOMAB phantoms to obtain accurate efficiency calibrations to quantify activity in the body. Table A1 contains average height and weight values for diff

28、erent ages. The data were taken from the National Health and Nutrition Examination Survey (NHANES) for the years 19992002. The data represent an average of several ethnic groups including Caucasian, non-Hispanic black, and Mexican American. The specific data for Mexican-Americans were typically 10%

29、lower than the average values. Dimensions for the different BOMAB phantoms shown in Tables A2 through A6 were calculated based on the NHANES data in Table A1 to scale from the reference BOMAB dimensions. The torso section of the 95th percentile phantom is quite heavy and can be difficult to handle.

30、The Human Monitoring Laboratory in Canada has divided their torso section into two pieces for ease of handling. For the purposes of this standard a two-piece torso section is acceptable with the caveat that the total phantom dimensions must be within the specified tolerances. The appropriate amount

31、of potassium should be incorporated into a phantom for applications such as estimating MDA or estimating background count rates from people. This requires a phantom to contain a representative amount of potassium. Table A7 contains suggested values for the potassium content of phantoms of different

32、sizes. The total mass of potassium added to the different sizes of BOMAB phantoms should be within 20% of the mass values in Table A7. The potassium should be homogeneously distributed in the filler material. The amount of potassium added to the phantom should be factored into the calculation of the

33、 radiation interaction coefficients for the phantom.Table A1.

41、 a reference BOMAB phantom. Right circular cylinders are used for the neck, arms, and legs; elliptical cylinder-shaped containers are used for the head, thorax, and abdomen. In the original design, the suggested orientation for the head section is rotated 90 degrees along the vertical axis of the ph

42、antom from the position shown. Fig. B2 illustrates the semi-major axis, semi-minor axis, and height dimensions of the BOMAB containers. Tables B1 through B4 contain historical information on the BOMAB dimensions. These data were used to help derive the tolerances for the BOMAB dimensions and volumes

43、 used in this standard. Table B1 contains information on the dimensions of the BOMAB phantom used by Delafield in a 1974 report that describes neutron capture probability related to sodium activation in the body. The wall thickness for this phantom design was 0.48 cm. Table B2 contains volume data f

44、or the BOMAB phantom described in a 1962 article by Sanders et al. showing the relationship between neutron dose and 24Na production in anthropomorphic phantoms. The upper and lower torso sections for this style of phantom correspond to the abdomen and thorax sections, respectively, that are describ

45、ed in the other BOMAB phantom references. The data in Table B3 are for a BOMAB phantom described in a 1949 article by Bush that describes a methodology for calculating auto-integral doses from homogeneously distributed radioactive material in the body. A density of 1 g mL1was assumed to determine th

46、e 68,300-cc volume. The data in Table B4 are for a BOMAB phantom described in a 1946 article by Bush that pertains to estimating energy absorption in the body from radium therapy. The data in Table B5 are taken from ICRU 48. The lengths of the phantom arm sections are not specified. The height of th

47、e reference adult male phantom is given as 180 cm. This measurement is 10 cm taller than the previously defined phantoms and is due to the head sections height (30 cm) being 10 cm greater than the height of the head sections for other BOMAB designs. The height of the reference adult female is given

48、as 160 cm, the reference 4-year-old as 105 cm, and the reference 10-year-old as 140 cm. Fig. B1. BOMAB phantom. ANSI/HPS N13.35-2009 10 Height Table B1. BOMAB dimensions from Delafield (1974).
