This paper provides a collection of data relevant to the use of various types of semiconductor detector in nuclear spectroscopy and gives examples of the use of detectors in specific experimental applications. Basic data on absorption of various kinds of radiation in germanium and silicon are given, and these are related to the characteristics of different types of semiconductor detectors. A br...
dear editor: the nuclear denotation due to the leakage from nuclear electricity plant in japan after the giant tsunami is a great concern. there are many possible health effects including induction of ophthalmic disorder on the affected population to the nuclear denotation. indeed the observation on the effect of radioactive leaking from the nuclear plant after the well-known nuclear leakage ...
General aspects of applying the method of retrospective dose estimation by electron paramagnetic resonance spectroscopy of human tooth enamel (EPR dosimetry) to the population residing in the vicinity of the Semipalatinsk nuclear test site are analyzed and summarized. The analysis is based on the results obtained during 20 years of investigations conducted in the Medical Radiological Research C...
The Collinear Resonance Ionization Spectroscopy (CRIS) experiment at ISOLDE, CERN, uses laser radiation to stepwise excite and ionize an atomic beam for the purpose of ultra-sensitive detection of rare isotopes, and hyperfine-structure measurements. The technique also offers the ability to purify an ion beam that is heavily contaminated with radioactive isobars, including the ground state of an...
while the introduction of radioactive tracers in the study of metabolic pathways has been well-documented in clinical thyroidology as early as 1924, the widespread utilization in other clinical specialties has been hampered by slow developments in radiation-detecting devices and in the production of appropriate radiopharmaceuticals, in addition tothe morbid fear of radiation. in the philippines...

VHSIC Hardware Description Language (VHDL) simulation of trapezoidal filtering algorithm was done. The exponentially decaying sequences were considered as the input to the filter. Such kinds of signals are usually obtained after processing (i.e. in analog domain) and digitizing the nuclear detector signals. The trapezoidal filter acts as a pulse shaping filter in a typical nuclear spectroscopy ...
Health problems after a nuclear crisis are aninteresting issue in medicine. After the recentJapanese nuclear crisis, several health issuesunderwent monitoring. There are few considerationson mucocutaneous diseases. Indeed, there is nodoubt that the skin and mucocutaneous issues arethe main organs affected by leaked radiations. It isimportant to take care of mucocutaneous lesionsin acute radiati...
Positron Annihilation Spectroscopy is a valuable microscopic method to study radiation damage in nuclear reactor pressure vessel steels. At SCKoCEN, a new positron lifetime setup, suited to measure positron lifetimes in irradiated steel, is being constructed. The particularity of this setup is that the prompt count rate originating from the induced 60Co-activity in the steel is highly reduced. ...
