RADAR Services



Many services that RADAR offers are directly available from this web site - access to data, downloads of decay data, dose conversion factors, documents, etc. In addition, other services are available, on-line, or through direct contact with RADAR members.

TRAINING COURSES

RADAR members are developing training courses in a number of areas in internal and external dose assessment. These courses may be available on-line, so that they can be taken over the Internet, thus reducing the high costs of attending courses in person. However, if desired, on-site training can also be contracted from specific individual(s) within the group on specific topics.

GENERAL CONSULTING

Members of RADAR are generally available for consultation on specific topics or for participation on specific projects involving internal and external dose assessment. Areas of expertise for each member are outlined on that memberīs biography page. Specific availability, rates, and contact information can be obtained from these pages. Examples of areas covered:

External Dose Calculations (John Hunt)

External dose assessments can be performed:

  • The effective dose or tissue dose can be calculated using an anthropomorphic phantom (voxel based). The exposure to any radionuclide in any geometry (point, plane or cloud immersion) can be simulated. The calculation may be made for normal exposure conditions or for accident cases, such as a point source in contact with the skin.
  • Dose calculations due to external radionuclide sources using existing dose conversion factors with modifications for specific installations or accident situations.

Nuclear Medicine Study Planning (Jeff Siegel or Mike Stabin)

  • Design of kinetic studies to obtain kinetic data in patients for use in dose calculations
  • Set up, calibration, and quality assurance procedures for nuclear medicine camera systems.
  • Calculations for data obtained in patients – quantification of region of interest data, marrow uptake, etc.

Internal Dose Calculations

  • For new radiopharmaceuticals, fitting animal or human kinetic data to models, and performing theoretical calculations for general use in nuclear medicine. (Rick Sparks or Mike Stabin)
  • For specific data from individual patients in nuclear medicine, image quantification, kinetic model development and individual dose calculations performed. (Rick Sparks or Mike Stabin)
  • For radiation workers, bioassay data can be evaluated and fit to available models, giving an estimate of the workerīs intake and committed dose. (Mike Stabin)
  • In radiation accidents, evaluation of external or internal doses received, based on measurements, models, observations, etc. can be performed. (Mike Stabin or John Hunt)
  • Orientation on the use and modification of input parameters for the various kinetic and dosimetric models currently recommended by the ICRP and IAEA. (Mike Stabin)
Projection, Implementation and Optimization Of Whole Body Counters And Bioassay Laboratory Facilities, including: (John Hunt)

  • building and laboratory characteristics and requirements,
  • shielding design,
Including advice on the:
  • selection of commercially available detection systems, associated electronics and softwares for spectrum analysis;
  • development of computer applications for report release and record keeping;
  • implementation of in vivo and in vitro monitoring programs;
  • establishment of routine calibration procedures
  • implementation of QA/QC programs in accordance with ISO Guides requirements;
  • development of anthropomorphic phantom for specific needs
  • optimization of available detection systems and measurement procedures
  • evaluation of sensitivity x official standards
In-vivo Counting System Calibration (John Hunt)

Calibration of in vivo systems using Monte Carlo techniques. An anthropomorphic phantom (voxel based) is used to simulate internal contamination. Any detector system and position, any organ and radionuclide may be simulated.

Software Development (Rick Sparks or Mike Stabin)

Members of RADAR have developed a number of software packages that have been used for various applications, and are continuing to develop and distribute useful software packages. If desired, member can be contracted to develop software for specific new applications of interest to users.
