Topics for the MARC XI conference will continue along the themes from previous conferences. Specific information regarding the sessions is provided below and may change as abstracts are submitted and evaluated. Some sessions have additional information (descriptions) and will be available if you click on the title. Please contact the session organizer or the Program Chair, Sam Glover, with any questions.

1. General Call for Papers
Organized by S. Glover, National Institute for Occupational Safety and Health, USA and S. LaMont, Los Alamos National Laboratory, USA

Description
This category is used for submission of papers which may not fit well into the existing sessions or the author is unsure which session is the best fit. All papers submitted in the General Call will be assigned an appropriate session.

2. Quality Assurance Topics in Radioanalytical Chemistry: Attribution to Root Cause
Organized by K. Inn, NIST, USA; and S. Jerome, National Physics Laboratory, UK

Description
QA/QC forensic analysis leading to root cause remediation is the focus of this session that will embrace investigative studies with high-level radiochemical expertise, and document the lessons learned.

Analytical radiochemistry quality assurance [QA] and quality control [QC] are not spectator sports. Neither one is an end to themselves. Dependable, reliable, accurate, precise, ground-truth, take-to-the-bank, are all attributes we want to stand with our scientific conclusions, decisions, recommendations, and theories in both practice and research. Quality control and quality assurance practices are key to building strength into these attributes. Such activities lend invaluable support to acquiring and maintaining accreditation to standards such as ISO 17025:2005.

This session will explore and examine new and improved tools for monitoring analytical radiochemical measurements, e.g., measurement quality objectives, reference materials, performance testing, audits, acceptance criteria, graphics, statistics, experimental design. However, to make QC/QA meaningful, vigilance and critical thinking must be constantly exercised. Early signatures of process deviations and bias need to be forensically analyzed and attributed, and the root cause remediated.

3. Current Needs and Future Challenges for Nuclear & Radiological Reference Materials & Proficiency Testing Materials
Organized by J. Mann, National Institute for Standards and Technology

Description
A robust supply of Reference Materials (RMs) and Proficiency testing (PT) materials is needed to ensure the quality of analyses performed for a range of nuclear and radiological applications including bioassay, environmental, emergency response, food safety, forensics, medical, nuclear power plant decontamination-decommissioning, nuclear safeguards, nuclear terrorism, public safety, and treaty monitoring. RMs and PT materials provide the foundation for accurate and precise measurements which provide the credible data necessary for developing, testing, and validating nuclear and radioanalytical methods. Without RMs for accurate measurements, policy makers would have difficulty making informed and responsible decisions based on analytical data that would stand up to scientific, public, and judicial scrutiny. The objective of this session will be to develop actionable RMs and PTs for the identified areas of need and to generate a list of point persons to champion these RMs and PT materials.

5. Radioecology studies in support of Fukushima
Organized by G. Steinhauser, University of Hannover, Germany; T. Nakanishi, University of Tokyo, Japan

Description
The Fukushima nuclear accident has caused significant releases of radionuclides into the environment. This session welcomes radioecological contributions to this topic. This includes classical radioecology in any environmental media, food safety, human and environmental health aspects, environmental nuclear forensics, and others. The comparison with other accidents is welcome. We also welcome presentations on methodological advances in radionuclide analysis, especially on the understudied radionuclides that may be related to nuclear accidents.

6. Ultra-sensitive Mass Spectrometric and Radiometric Methods for Environmental and Space Applications
Organized by P. Povinec, University of Bratislava, Slovakia

Description
Recent developments in mass spectrometric methods (e.g. AMS, ICPMS, TIMS, LIMS, RIMS, SIMS, …), as well as in radiometric methods (e.g. underground gamma- and beta-ray spectrometry, shielding of detectors from cosmic radiation, coincidence-anticoincidence systems,…) have improved considerably the sensitivity of analysis of cosmogenic, primordial/radiogenic and anthropogenic radionuclides, which decreased a sample size required for environmental studies. These developments have allowed to carry out investigations, which were not possible before either because of the lack of sensitivity, or availability of suitable samples. A wide range of applications of ultra-sensitive techniques with applications in environmental and space applications will be covered as well.

18. Development and Application of Nuclear Analytical Methods with Neutron Beam Technologies.
Organized by L. Cao, Ohio State University, USA; and G. Downing, NIST, USA.

Description
One breach of nuclear analytical methods is involved of using a collimated neutron beam for non-destructive materials analysis and characterization. The neutron beam could be using fast neutron as produced by a neutron generator for in-field applications, or a stationary neutron source such as a research nuclear reactor that could deliver either thermal or cold neutron beam for a high sensitive materials probing. A recent successful application of neutron beam technology is for characterizing lithium atoms inside a Li-ion battery to assist the energy storage studies. The development and application of neutron-based techniques is welcome to this session, which includes but not limited to neutron depth profiling, prompt gamma neutron activation analysis, neutron imaging, etc. Development of neutron generator, advanced sensor and instrumentation are also invited to this session.

One branch of nuclear analytical methods involves using synchrotron radiation techniques for non-destructive material analysis and characterization. Synchrotron radiation (SR) based techniques have been utilized with increasing frequency in the past decade to explore the brilliant and challenging sciences of nuclear materials. This trend is partially driven by the basic needs for multi-scale actinide speciation and bonding information and also the realistic needs for nuclear energy research. In this session, recent research progresses on nuclear materials by means of various SR techniques (with emphasis on X-ray absorption spectroscopy, X-ray diffraction and scattering spectroscopy) will be presented and discussed..
