Design, construction, and analysis of a skin contamination dosimeter

Creator:: Cazalas, Edward J.
Abstract:: International recommendations provided by the International Commission on Radiation Protection (ICRP), as well as national regulations, set by the U.S. Nuclear Regulatory Commission (NRC), state that the exposure of skin to highly concentrated radioactive sources should be monitored at specified depths in skin and kept below specific dose equivalence levels....

Human Eye Dosimetry: Air Gap Analysis by Shield Placement and Photon Energy

Creator:: Herrera, Joshua P.
Abstract:: When the ICRP updated their recommended limits for eye dose, they ignited a renewed interest in eye dosimetry. Especially, how the updated eye dose estimates affect current regulations and what that would mean to a radiation worker. Radiation workers are commonly required to wear leaded eyeglasses to reduce their dose...

Locating and Quantifying Contamination Deposited in Radiation Puncture Wounds

Creator:: Wehmann, Nicholas K.
Abstract:: Internal dosimetry models show a representation of how radionuclides move through the body. This study takes a look at radiation wounds by modelling a puncture wound to the hand using Microshield software. An analysis of these models provides a triangulation method that could be used to investigate wound characteristics, as...

Site specific reference person parameters and derived concentration standards for the Savannah River site

Creator:: Stone, Daniel K.
Abstract:: The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...

Comparison between AAPM's TG-21 and TG-51 clinical reference protocols for high-energy photon and electron beams

Creator:: Nes, Elena M.
Abstract:: In radiation therapy it is very important to accurately measure the amount of radiation delivered. The effectiveness of the treatment depends on delivering the dose with an accuracy of 5% or better. The dosimetry in different clinics must also be consistent. For these reasons national and international calibration protocols have...

Skin depth dose distribution measurement and analysis using radiochromic dosimetry

Creator:: Thuo, Kellen K.
Abstract:: Compliance with 10CFR 20.101 requires that exposure to the skin be assessed at a depth of 0.007 cm over 10 cm² area. This depth generally corresponds to the interface between the epidermal and dermal layers of the skin. The Nuclear Regulatory Commission states the criteria for evaluating skin dose from...
Resource Type:: Masters Thesis
Full Text:: an optical change on the film is quantified to radiation dose. Dosimetry film is often used when

Development of a dose conversion factor from uptakes of Po-210 through smoking using a modified ICRP 30 lung model

Creator:: Hout, Jason D.
Abstract:: A thesis presented on the determination of factors related to deposition, clearance, and dosimetry of the ICRP 30 lung model as related to smoking. Variations in calculations used to determine radiation doses leave a need to determine a standard method to determine absorbed dose from smoking. Standard parameters are used...

Characterization of the onset of charged particle equilibrium for photon dose to skin

Creator:: Ryan, Michael C.
Abstract:: In the U.S., the Nuclear Regulatory Commission (NRC) is responsible for setting annual dose limits. For cases of hot particle contamination these limits are set at depths in skin of 7 mg/cm², 300 mg/cm², and 1000 mg/cm². However, at such shallow depths, the lack of charged particle equilibrium (CPE) precludes...

Preliminary investigation of X-ray imaging for dose extraction of BANG® polymer gel in intensity modulated radiation therapy

Creator:: Sath, Chhipo
Abstract:: This study investigated gel dosimetry with X-ray CT imaging as a possible means for extracting dose information from a 3D gel dosimeter. Currently Optical CT and MRI are the popular means of dose extraction, but X-ray CT imaging has the advantage of being more convenient and cost effective. The dosimetric...

Dosimetric verification of respiratory gated radiation therapy for tumors involving the lung

Creator:: Webb, Lindsey S.
Abstract:: As the field of radiation therapy evolves new treatment techniques will be established. An example of an evolving treatment technique is respiratory gated radiation therapy (RGRT). Research and studies have shown that RGRT can be used to account for tumor motion as a result of respiratory motion. With evolving technology...
