Dr. Landsberger is primarily involved in the determination of heavy metals in environmental samples using nuclear analytical methods. He has had experience many years of experience in analyzing air samples from the Arctic, Great Lakes, and other urban and rural areas. In particular he has developed improved nuclear techniques to better determine the elements of critical importance in identifying regional sources of airborne particles, and characterizing solid waste leaching dynamics. His current research interests include low-level counting of natural radioactivity, corrosion studies, Compton suppression gamma-ray spectrometry and risk assessment in radioactivity handling.

Fields of Specialization:

Radioactive Waste Management
Health Physics
Neutron Activation Analysis
Low-Level Counting
Long Distance Air Transport of Heavy Metals
Solid Waste Management and Leaching Dynamics
