Noun1.neutron radiation- radiation of neutrons (as by a neutron bomb) ionizing radiation- high-energy radiation capable of producing ionization in substances through which it passes corpuscular radiation,particulate radiation- a stream of atomic or subatomic particles that may be charged positively (e...
a. External Radiation. External irradiation can be defined as radiation entering the body and tissues from some source outside the body. This could be from a point source, such as an X-ray machine or linear accelerator, or a more generalized exposure, such as cosmic irradiation. Exposures can...
This is largely due to a substantial level of uncertainty associated with carcinogenesis below a dose of 100 mSv. To date, the most robust data come from the 120,000 Japanese atomic bomb survivors, who form the Life Span Study (LSS) cohort and continue to be studied by the Radiation ...
The effects of random dose measurement errors on analyses of atomic bomb survivor data are described and quantified for several analytical procedures. It is found that the ways in which measurement error is most likely to mislead are through downward bias in the estimated regression coefficients and...
The chlorine stems from nuclear testing in the 1950s and 60s. Studying chlorine levels lets scientists paint a picture of the Earth's climate history. The team wants to drill deeper and discovery if there are any other surprises in the past. We still have a lot to learn about how ice st...
In June 1954, a hydrogen bomb was exploded over Eniwetok in the Pacific, which had 1000 times the power of the Hiroshima and Nagasaki bombs, and radioactive fallout _ 1341 Table II Classification of parents by exposure (after Neel and Schull, 1956) Distance from hypocentre Shielding Symptoms,...
The phenomena that astonished Rutherford little more than a hundred years ago occurred when a minority but nonetheless a significant number of α particles were detected being reflected from a thin metal foil. He is said to have remarked that it was as if he had ‘fired a 15-in. shell at...
Either it is a patient of his own or the circumstances (e.g., from drugs and syringes lying around or through information from relatives). Examples are exacerbation of diabetes to coma, apoplectic insult, digitalis intoxication, etc.).

A threshold dose for lens opacities of greater than 1 Gy was initially established in atomic bomb survivors, but this threshold has since been lowered to approximately 0.5 Gy when latency times were lengthened to 50 years or more [4]. Data from radiotherapy patients and medical workers yielded...
