Countermeasures for radiocesium in animal products in Norway after the Chernobyl accident--techniques, effectiveness, and costs

Nine years after the reactor accident in Chernobyl contamination by radiocesium is still a significant problem in sheep and reindeer production in Norway. To reduce the impact of the accident, effective countermeasures had to be developed and implemented. The levels of radiocesium in meat were reduced by a combination of countermeasures such as special feeding, use of cesium binders (bentonite and Prussian blue), and changing of slaughtering time. The countermeasures were labor intensive and expensive. Costs per averted dose per person-Sv were calculated to range from NOK 1,000 to 100,000 (7 NOK = $1 U.S.), with the use of cesium binders being the least expensive and condemnation of meat the most costly. Dietary advice, which did not include any compensation costs, had a cost of NOK 40 per person-Sv. Apart from the rejection of meat in 1986, countermeasures were deemed to be justified on a cost-benefit basis (less than NOK 600,000 per person-Sv).

Suppression by gangliosides of polymerization of glial cytoskeletons prepared from rat astrocytes: a role of sialic acid moiety

There are three reasons for giving serious consideration to technological countermeasures against driver fatigue: 1, fatigue is a persistent occupational hazard for professional drivers; 2, some professional drivers are under considerable pressure to reach their scheduled destination, in spite of feeling drowsy; 3, fatigue adversely affects an individual's ability to assess their own fitness to continue driving. However, there are two reasons for exercising caution in implementing technological countermeasures: 1, their reliability under real traffic conditions is largely unproven; 2, they could be used by unscrupulous drivers to support the continuation of journeys that should have been terminated because of human impairment. This paper draws on the findings of research into the origins, symptoms and development of human fatigue, and on recent research into driver-support systems, to assess the prospects for implementations of technological countermeasures against driver fatigue in the foreseeable future.
