“…As stated by Becker et al, “Different scenarios can be simulated and situations with highest exposures can be revealed” (Becker et al 2011 ). Simulations using voxel phantoms or flexible mathematical phantoms are useful tools for studying hand exposure (Becker et al 2008a , b , 2011 , 2014 ; Blunck et al 2009 , 2011 ; Becker and Blunck 2011 ; Figueira et al 2013 ).…”

The dose limit for the skin of the hand is typically converted to a surface of 1 cm2, which means that one needs to measure point doses in different places on the hand. However, the commonly used method of measuring doses on the hand, i.e., using a dosimetric ring including one or several thermoluminescent detectors worn at the base of a finger, is not adequate for manual procedures such as labeling or radiopharmaceutical injection. Consequently, the purpose of this study was to create and conduct a series of computer simulations that, by recreating the actual working conditions, would provide information on the values of ionizing radiation doses received by the most exposed parts of the hands of employees of radiopharmaceutical production facilities, as well as those of nurses during the injection of radiopharmaceuticals. The simulations were carried out using Monte Carlo radiation transport calculations. The Hp(0.07) personal dose equivalent values obtained for the fingertips of the index and middle fingers of nursing staff and chemists were within the range limited by the minimum and maximum Hp(0.07) values obtained as a result of dosimetric measurements carried out in diagnostic and production centers. Only in the case of the nurse’s fingertip, the simulated value of Hp(0.07 slightly exceeded the measured maximum Hp(0.07) value. The comparison of measured and simulated dose values showed that the largest differences in Hp(0.07) values occurred at the thumb tip, and for ring finger and middle finger of some of the nurses investigated.

“…One task was to develop a method, to model handling scenarios on the information of images taken and to simulate them with a Monte Carlo code like MCNPX. Simulations using voxel hand phantoms or flexible mathematical hand phantoms are useful tools to investigate the hand exposure [2]. In particular for the case of inhomogeneous radiation fields, where measurements could be difficult, time consuming or not feasible at all, simulations are advantageous.…”

To evaluate extremity doses and optimize radiation protection of medical staff, we investigated examples in nuclear medicine and CT fluoroscopy. In addition to measurements with medical staff on-site and with real hand phantoms, selected scenarios were simulated with hand phantoms. Besides simulations of static hand poses also modeling based on consecutive frames from video recordings during handling scenarios was realized. These procedures are useful tools to reveal highest exposures which in turn could promote initiating optimized radiation protection measures.

Among the various incidents in industrial radiography, inadvertent handling of sources by hands is one of the most frequent incidents in which some parts of the hands may be locally exposed to high doses. An accurate assessment of extremity dose assists medical doctors in selecting appropriate treatments, preventing the injury expansion in the region. In this study, a phantom was designed to simulate a fisted hand of a radiographer when the worker holds a radioactive source in their hands. The local doses were measured using implanted TLDs in the phantom at different distances from a source. Furthermore, skin dose distribution was measured by Gaf-chromic films in the palm region of the phantom. The reliability of the measurements has been studied via analytical as well as Monte-Carlo simulation methods. The results showed that the new phantom design can be used reliably in extremity dose assessments, particularly at the points next to the source.
