Evaluation of High Level Environmental Background Radiation Areas and its Variation in Ramsar

Introduction The exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. For most individuals, this exposure exceeds that from all man-made sources combined. Materials and Methods In this study, the annual effective dose in high level environmental background radiation areas (HLEBRAs) of northern city of Ramsar in Iran was de...

Evaluation of public exposure in high background natural radiation areas (HBNRAs) of Ramsar

Some areas in Ramsar, a northern city of IRAN, have the most natural radiation level in the world which is due to high concentration of 226Ra and its daughter products specially 222Rn and therefore these regions have been interested for radiation related investigations. The aim of this study also has been to evaluate public exposure in such areas in Ramsar, in order to obtain up to date informa...

Automatic Interpretation of Vegetation Areas in Brazil

This paper describes a procedure for a multitemporal interpretation of vegetation areas in Brazil using Landsat TM images. We started with a monotemporal interpretation of the first epoch of the scene by using both spectral and structural features. For interpretation of temporal changes we discretely described temporal conditions of regions, and transferred the most probable temporal changes of...

Interpretation advances in noisy data areas

Noisy data are often resigned to the “too hard” basket, and an expectation exists that incremental improvements in processing effort and technology will slowly recover interpretation confidence over a long period of time. Fortunately, acquisition technology has improved significantly in recent years, and high-density 3D acquisition methods (multi-streamer, OBC, and land) are now able to provide...
