- The ECOSYS model is the ingestion dose model integrated in the ARGOS and RODOS decision support systems for nuclear emergency management. The parameters used in this model have however not been updated in recent years, where the level of knowledge on various environmental processes has increased considerably. A Nordic work group has carried out a series of evaluations of the general validity of current ECOSYS default parameters. This paper specifically discusses the parameter revisions required with respect to the modelling of deposition and natural weathering of contaminants on agricultural crops, to enable the trustworthy prognostic modelling that is essential to ensure justification and optimisation of countermeasure strategies. New modelling approaches are outlined, since it was found that current ECOSYS approaches for deposition and natural weathering could lead to large prognostic errors.

- Depression is a common and serious disorder that may have developmental origins. Birth-related factors have been related to childhood and adult occurrence of somatic as well as psychiatric disorders, but studies on the relationship between birth-related factors and depression are few and show mixed results. In addition, varying methods have been used to assess depression. Standardized clinical criteria to diagnose depression, combined with birth data collected from midwife records have not been used in most studies. Participants in the Prospective Population Study of Women in Sweden (803 women), born 1914, 1918, 1922 and 1930, provide information on birth factors and depression. Women participated from 1968 at mid-life ages of 38-60years, to 2000, when they were age 78-92years. Original birth records containing birth weight, length, head circumference, and gestational time, as well as social factors were obtained. Lifetime depression was diagnosed via multiple information sources. Symptoms were assessed using the Comprehensive Psychopathological Rating Scale and diagnoses were based on DSM-III-R criteria. Over their lifetime, 44.6% of women in this sample experienced depression. Birth weights≤3500g [odds ratio (OR), age-adjusted=1.72; 95% CI 1.29-2.28, P<0.001] and shorter gestational time (OR, age-adjusted=1.13; 95% CI 1.04-1.24, P=0.005) were independently associated with a higher odds of lifetime depression in a logistic regression model adjusted for age. Lower than median birth weights and shorter gestational time were related to lifetime depression in women. Both neurodevelopmental and environmental contributions to lifetime depression may be considered.

Consequences of severe radioactive releases to Nordic Marine environment
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consequences of hypothetical severe radioactive releases to Nordic marine environment – the Baltic Sea and the North Atlantic - has been considered. As a reference, releases from a 3000 MWth nuclear power plant reactor size was used for the Baltic Sea area accidents. Individual dose to human could be ten to some hundreds of millisieverts in local sea area. In the Baltic Sea area, individual dose was 0.01 mSv after one year and 0.1 mSv after five years from the release event. The collective dose estimate was 880 manSv. In case of hypothetical submarine accidents at the North Atlantic, the marine fluxes are important factors. According to simulation results, e.g. maximum concentration near the source region at the Icelandic coast sinks below 1% only after 300 days. Consequences of an accident of a modern submarine for e.g. to Kattegat region was calculated. The arising doses can be equal or higher than from natural sources. The models predictions seem to reach nice consistence with measured values in qualitative and quantitative considerations.
