Fallout Radiation

SummaryA medical survey of the Marshallese people in March 1959, five years after exposure to fallout radiation, showed that the people had recovered from the acute effects of their radiation exposure and appeared to be generally in good health. The following specific statements can be made in regard to their radiation health status:1. No illnesses or diseases were found that could be directly associated with acute radiation effects.2. One case of cancer and three deaths have occurred, but with no direct relation to radiation effects.3. Fertility does not appear to have been affected. The incidence of miscarriages and stillbirths appears to be somewhat higher than in the unexposed Marshallese, but a deficiency of vital statistics precludes definite conclusions as to whether or not this is a radiation effect.4. Suggestive evidence of slight lag in growth and development of exposed children noted previously is being re-evaluated on the basis of better age data obtained during the latest survey.5. Blood platelet levels are within the normal range but somewhat below that for the unexposed population.6. Only 12 cases show residual changes in the skin from beta burns. None show any evidence of cancerous change.7. Possible late effects of radiation such as shortening of life span, premature aging, increased incidence of leukemia and malignancies, increased incidence of degenerative diseases, opacities of the lens of the eyes, and genetic changes have not been detected.8. The original body burdens of internally absorbed fission products appear to be too low to have produced any acute or to be causing long-term effects.9. The return of the people to the slightly contaminated island of Rongelap has resulted in some increase in body burdens of Cesium137, Zinc65 and Strontium90. However, the levels are far below the accepted maximum permissible limits and it is not believed any untoward effects will result.

Local Strain Rate

Investigation of frictional forces -Experimental techniques and working conditions in the high voltage electron microscope have already been described (1). Care has been taken in order to minimize both surface and radiation effects under deformation conditions.Dislocation densities and velocities are measured on the records of the deformation. It can be noticed that mobile dislocation densities can be far below the total dislocation density in the operative system. The local strain-rate can be deduced from these measurements. The local flow stresses are deduced from the curvature radii of the dislocations when the local strain-rate reaches the values of ∿ 10-4 s-1.For a straight screw segment of length L moving by double-kink nucleation between two pinning points, the velocity is :where ΔG(τ) is the activation energy and lc the critical length for double-kink nucleation. The term L/lc takes into account the number of simultaneous attempts for double-kink nucleation on the dislocation line.

Environmental Sem

The advent of the environmental SEM (ESEM) has made possible the examination of uncoated and untreated specimen surfaces in the presence of a gaseous or liquid environment. However, the question arises as to what degree the examined surface remains unaffected by the action of the electron beam. It is reasonable to assume that the beam invariably affects all specimens but the type and degree of effect may be totally unimportant for one class of applications and totally unacceptable for another; yet, for a third class, it is imperative to know how our observations are modified by the presence of the beam. The aim of this report is to create an awareness of the need to initiate research work in various fields in order to determine the guiding rules of the limitations (or even advantages) due to irradiation.
