Improvement of the AMS-technique and applications to 3H and 59Ni Measurements

Popular Abstract in Swedish Utveckling av AMS-tekniken och tillämpningar på 3H och 59Ni mätningar Traditionellt mäter man radioaktivitet genom att registrera den utsända strålningen från sönderfallande kärnor. Denna sönderfallsmätning fungerar oftast bra så länge halveringstiden (den tid det tar för hälften av kärnorna att sönderfalla) är kort nog samt då man har tillräckligt mycket material. MetAccelerator mass spectrometry (AMS) is a highly sensitive technique for counting atoms. Its main advantage in comparison with radiometric methods is the smaller amount of sample required (by a factor of a thousand). The method has a high efficiency and requires only some ten mg of sample material. The radioisotope 59Ni is of great importance in nuclear waste management in the nuclear industry. Thi

PATIENT DOSES IN COMPUTED TOMOGRAPHY EXAMINATIONS IN TWO REGIONS OF THE RUSSIAN FEDERATION.

Computed tomography (CT) is often a justified diagnostic tool, but is also associated with high exposure of the patients. Due to the rapid increase in the number of CT units and thus the availability of CT examinations in Russia, there is a growing need for optimisation within this field. In order to develop proper optimisation procedures for CT, the two regions St. Petersburg and Belgorod of Russ

Adverse events and their relation to mortality in out-of-hospital cardiac arrest patients treated with therapeutic hypothermia.

OBJECTIVES:: To investigate the association between adverse events recorded during critical care and mortality in out-of-hospital cardiac arrest patients treated with therapeutic hypothermia. DESIGN:: Prospective, observational, registry-based study. SETTING:: Twenty-two hospitals in Europe and the United States. PATIENTS:: Between October 2004 and October 2008, 765 patients were included. INTERVE

Monte Carlo calculations of absorbed doses in tumours using a modified MOBY mouse phantom for pre-clinical dosimetry studies.

Abstract Background. Clinical treatment with radionuclides is usually preceded by biokinetic and dosimetry studies in small animals. Evaluation of the therapeutic efficacy is essential and must rely on accurate dosimetry, which in turn must be based on a realistic geometrical model that properly describes the transport of radiation. It is also important to include the source distribution in the do

Laser-Induced Incandescence for Soot Diagnostics: Theoretical Investigation and Experimental Development

Popular Abstract in Swedish Mer än 75 % av energianvändningen i världen kommer idag från förbränning av fossila bränslen, biobränslen och avfall. Trots att alternativa energikällor är på framfart kommer förbränning stå för den största andelen av världens energianvändning även de kommande decennierna. Tyvärr medför förbränning flera negativa konsekvenser, såsom ökad koldioxidhalt i atmosfären och uLaser-induced incandescence, LII, is a laser-diagnostic technique that can be used to measure the volume fraction and the sizes of soot particles suspended in a gas, such as within a combustion process or in its exhausts. The technique is based on the facts that the time-decay of the radiation from laser-heated soot particles is directly related to the particle size in the probed volume, and that
