Check TLD calculations and reports to outside institutions for accuracy.
Communicate with physicists at outside institutions regarding irradiation questions and discrepancies identified by the quality assurance services.
Provide backup to the monitoring of the TLD service to insure timely processing of various outreach services.
Gain and use knowledge of radiation measurement procedures, including dosimeter readout and calculations, for RDS activities to improve efficiency and accuracy.
Assist with maintenance and troubleshooting of lab equipment.
Weekly irradiations of standard and control TLD in a Cobalt-60 beam at the MD Anderson Accredited Calibration Dosimetry Laboratory (ADCL) .
Additional irradiations as needed for new batch checkout, experiments, and problem solving.
Programming & Problem Solving
Maintain Microsoft Access database and programs. Update code to new languages or commercial software where suitable.
Work with the team to develop, test and implement new software to further automate RDS processes, including shipping, billing, and dosimeter processing.
Isolate and resolve software/hardware problems.
Provide technical documentation for applications to include system change and maintenance procedures.
Provide assistance to the computational scientist as needed.
Other duties as assigned.

About MD Anderson Cancer Center
We work at an amazing place. A place of hope. A part of something big. We’re one of the largest and most renowned cancer centers in the world. Have a history of serving patients for more than 70 years and more than 20,000 strong – faculty, staff, volunteers, friends – and we’re all dedicated to our bold, ambitious mission; fighting cancer. We are MD Anderson. We’re Making Cancer History®.
This position will be in the Division of Radiation Oncology, Department of Radiation Physics, Section of Outreach, Radiation Dosimetry Services (RDS) & Late Effects Studies. The RDS has highly qualified and very dedicated faculty and staff, many of whom have worked at RDS for over thirty years. In total, the RDS has 17 faculty and staff members. We collaborate closely with the other sections within MD Anderson Outreach Physics, namely the Imaging and Radiation Oncology Core (IROC) Houston QA Center and the MD Anderson Accredited Dosimetry Calibration Laboratory .
For all of the services provided by RDS, thermoluminescent dosimeters (TLD) and associated apparatuses are mailed to and irradiated at requesting institutions. The irradiated TLD are mailed back to RDS where they are read and dos...es calculated using a well-established protocol with an uncertainty of ? 1.5 % (Kirby et al., 1992). Our system is calibrated with TLD standards irradiated using a 60Co unit at the MD Anderson Accredited Dosimetry Calibration Laboratory. The TLD dose measurements are compared to the institution’s stated dose and a report is issued to the institution for each beam or dose point checked.
