    Directional Correlation between Successive Internal-Conversion Electrons from Tantalum-181 (1949)
    [s.l.] : Nature Publishing Group
    Nature 163 (1949), S. 168-168 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] HAFNIUM-181 decays with a 48 day half-life to a 20-microsecond metastable state1 of tantalum-181. From this, two γ-rays are emitted in cascade, with internal conversion coefficients Ne/(Ne + Nγ) approximately 0.6 and 0.062. We wish ...

    Yttrium-90 in Gonads of Monkeys containing Strontium-90 (1970)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] A number of young adult monkeys Cercopithecus spp. received about 1 mCi/kg of an equilibrium mixture of 90Sr and 90Y by a single intramuscular injection3. The radioactivity of the ovary of one animal and of the testis of another was measured by standard methods after they died, 24 and 25 days ...

    Toxicity of Radiostrontium in Monkeys (1953)
    [s.l.] : Nature Publishing Group
    Nature 172 (1953), S. 122-123 
    Details

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] All the animals apparently died from ansemia; the haemoglobin, red-blood cell count and packed-cell volume fall in a remarkably consistent manner; the white-cell count always falls before the red-cell count. The amount of radiostrontium retained in the body at death was estimated from autopsy ...

    Delayed Toxicity of Radiostrontium in Monkeys (1955)

    Notes: [Auszug] The blood picture in the six animals did not seriously deteriorate following the injections until a sharp terminal fall shortly before death, as shown in the graph of packed cell volume (Fig. 1). In four of the animals, the hsematological findings were within normal limits until two or three weeks ...

    Radioactive Fall-Out in Ghana (1960)

    Notes: [Auszug] ROUTINE radioactive survey measurements were started in Ghana in October 1959, after the announcement of French atomic testing plans at Reggan in the northern Sahara. The measurements were extended in January 1960, and the first atomic explosion at Reggan was on February 13. It gave a peculiarly ...

    A.C. Operation of Ion Chambers (1953)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] The current produced by irradiation in the A.C. case is caused not primarily by the collection of ions but by the oscillation of a space charge within the chamber. This builds up slowly to its equilibrium density after a source of radiation is brought near the chamber, giving slow response time but ...

    Measurement of Radioactivity in Human Breath (1951)

    Notes: [Auszug] The first uses the a-radiation breath-monitor, type A.E.R.E. 1056.4. A four-litre specimen of the patient's exhaled breath is collected and drawn into an evacuated ionization chamber; the a-disintegra-tions in this sample are then counted. The second method permits continuous-flow measurements and ...
