At a nominal activity of 6 mCi (0.22 GBq), the absorbed dose rate at the front surface (i.e., reference dose rate) was measured by using an extrapolation ionization chamber (EC). The radiochromic film (RCF) was also used to measure the reference dose, axial depth dose distributions and transaxial dose profiles at various depths in water.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>\n                      <jats:bold>Results:<\/jats:bold>\n                    <\/jats:title>\n                    <jats:p>The reference dose rate was 3.89\u2009\u00b1\u20090.14 cGy\/s for EC and 3.84\u2009\u00b1\u20090.25 cGy\/s for RCF. The depth dose rate was reduced approximately by an order of magnitude for every 2 mm depth in water. Measured depth doses in depths of 0.5\u20132.5 mm agreed with Monte Carlo data within \u00b13%. Due to nonuniform absorption of P\u201032 into an absorbent disk, the dose profiles were not symmetric and decreased more rapidly toward the periphery than those predicted by the MC. The authors confirmed no leakage of P\u201032 activities and negligible exposure rate around the hand grip of the applicator.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>\n                      <jats:bold>Conclusions<\/jats:bold>\n                    <\/jats:title>\n                    <jats:p>: The P\u201032 applicator can deliver therapeutic doses to the surface of the conjunctiva, while sparing the lens better than Sr\/Y\u201090 applicators. The doses at any points from the P\u201032 applicator could be calculated by using the measured dosimetry data. They also confirmed no leakage of the source, reliable integrity of the applicator, and negligible exposure level around the hand grip of the applicator. However, due to a possibility of nonuniform distributions of P\u201032 in an absorbent disk, measuring dose profiles as well as the reference dose rate for every new applicator would be recommended.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1118\/1.3644843","type":"journal-article","created":{"date-parts":[[2011,10,26]],"date-time":"2011-10-26T18:05:12Z","timestamp":1319652312000},"page":"6143-6151","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["Dosimetry of a new P\u201032 ophthalmic applicator"],"prefix":"10.1002","volume":"38","author":[{"given":"Chang Heon","family":"Choi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyon Soo","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwang\u2010Jae","family":"Son","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ul Jae","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun Sig","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Won Ryang","family":"Wee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung Whan","family":"Ha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Il Han","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung\u2010Joon","family":"Ye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,10,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2003.12.021"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(83)90234-1"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00176295"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(94)31269-3"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0936-6555(05)81177-X"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00066-006-1484-1"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.174.2.2296667"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(92)90687-D"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(91)32051-7"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(94)90146-5"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.2896076"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.598841"},{"key":"e_1_2_7_14_1","unstructured":"(http:\/\/ie.lbl.gov\/education\/isotopes.htm)."},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.1376441"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.596632"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.598204"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.1709490"},{"key":"e_1_2_7_19_1","unstructured":"International Commission on Radiation Units and Measurements \u201cDosimetry of beta rays and low\u2010energy photons for brachytherapy with sealed sources \u201d ICRU Report 72 (ICRU Bethesda MD 2004)."},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3301574"},{"key":"e_1_2_7_21_1","volume-title":"Gafchromic EBT2 Self\u2010Developing Film For Radiotherapy Dosimetry","author":"Products I.
