Andreeva Bay in northwest Russia hosts one of the former coastal technical bases of the Northern Fleet. Currently, this base is designated as the Andreeva Bay branch of Northwest Center for Radioactive Waste Management (SevRAO) and is a site of temporary storage (STS) for spent nuclear fuel (SNF) and other radiological waste generated during the operation and decommissioning of nuclear submarines and ships. According to an integrated expert evaluation, this site is the most dangerous nuclear facility in northwest Russia. Environmental rehabilitation of the site is currently in progress and is supported by strong international collaboration. This paper describes how the optimization principle (ALARA) has been adopted during the planning of remediation work at the Andreeva Bay STS and how Russian-Norwegian collaboration greatly contributed to ensuring the development and maintenance of a high level safety culture during this process. More specifically, this paper describes how integration of a system, specifically designed for improving the radiological safety of workers during the remediation work at Andreeva Bay, was developed in Russia. It also outlines the 3D radiological simulation and virtual reality based systems developed in Norway that have greatly facilitated effective implementation of the ALARA principle, through supporting radiological characterisation, work planning and optimization, decision making, communication between teams and with the authorities and training of field operators.
Studies from several countries suggest that erecting fences on bridges more commonly used for suicide by jumping may be an effective way of reducing the risk of suicide by jumping from these bridges. Distribution of suicides by jumping off bridges has not yet been studied on a national level in any country. This study included all suicides by jumping from high places registered in the Norwegian Cause of Death Registry (COD) in the period 1999-2010 (n = 319). Combining data from the COD registry and information from police records, 71 cases of suicide by jumping off a bridge were identified involving 36 bridges. This form of suicide constituted approximately 1% of all suicides in Norway in the period 1999-2010. Almost half of these suicides were registered at only 6 bridges. Three Norwegian bridges were secured during the observation period of this study. Two bridges had barriers installed on the full length of the bridge with 11 suicides registered before barriers were installed, and none after. On the 1 bridge that was only partially secured, no change in numbers of suicides was observed after barriers were installed. One-third of jumps from bridges occurred over land. We found that although suicide by jumping off bridges was a relatively rare event, there is a potential for saving lives by installing physical barriers on bridges that are more commonly used for suicide by jumping.
In 1988 and 1990, respectively, Norway and Sweden adopted legal reforms including abandonment of mandatory jail sentences for persons driving with BACs above specific limits. Interrupted time-series analysis finds that in both countries traffic deaths diminished simultaneously with the reforms, consistent with the understanding that Scandinavian success in reducing impaired driving does not depend upon mandatory jail.
The Brazilian radiologist Manoel de Abreu (1892 - 1962) was the first who succeeded in developing an apparatus suitable for mass radiography of the chest in the fight against tuberculosis. Within a few years, many countries had started to use mass radiography. The German professor Hans Holfelder (1891 - 1944) improved the apparatus and made a transportable version to be used in special buses and in assembly halls. When Germany attacked Norway in April 1940, the Chief Tuberculosis Inspector Otto Galtung (1904 - 81), was making plans for a nation-wide screening programme with mass radiography. He was fired by the Nazis who continued his work and started screening in 1943. The first mass radiography in Norway was carried out in Bergen in September 1940. Almost 11 000 pupils and teachers from all schools in Bergen were examined under the management of Holfelder, then an SS-Standartenführer (colonel) and radiologist in the occupation force. The screening was performed in co-operation with the municipal health authority who bought the apparatus in spring 1941.
A nation-wide campaign aimed at preventing accidents in the home is being implemented in Norway. 95% of the municipalities acknowledge having received information material from the campaign, 33% report having established accident prevention committees, and 26% report having introduced preventive measures as a result of this national campaign. The study indicates that accidents are not recognized as yet as a major health problem in many municipalities. Identification of accidents as a health problem seems to be an important factor in the preventive efforts. To enhance further accident prevention efforts it seems important to increase awareness of accident as a health problem, and to increase the involvement of key personnel within the community.
Water fluoridation has not been introduced in Norway, although 99% of the population receive water with suboptimal fluoride levels. Alternative methods of fluoride prophylaxis have gained wide acceptance in this country. While less than 1% of the children received fluoride tablet in 1971, sales data in 1976 indicated a daily supply of fluoride tablets to 50% of the 0-5-year-olds and to 20% of the 6-11-year-olds. Most schoolchildren have joined mass prophylactic programs with regular with regular applications of fluoride solutions. Furthermore, fluoride-containing dentifrices have become available and are increasingly used. The increased use of fluoride has been paralleled by a marked reduction in caries and restorative need. During the past 5 years, a reduction of about 45% in the number of fillings inserted in 6-17-year-old children has been noted. In some areas, a 70% reduction has been recorded. The ratio between expenses for prophylaxis and savings in cost of treatment is favorable. The Norwegian Adverse Drug Reaction Committe received 34 case reports of adverse effects ascribed to fluoride prophylaxis, from 1970 to 1977. None of the 25 follow-up studies performed, suggested fluoride to have been responsible for the reported symptoms. In Norway, the benefits of fluoride prophylaxis are becoming increasingly evident.
