An Overview of Technological Developments in Medical Applications of X-Rays and Radioactivity

The years 1895 to 1898 were momentous for their impact on health and human well beings. First, Wilhelm Roentgen noted a glowing fluorescent screen, caused by invisible rays. This event subsequently led to the discovery of X-rays in 1895, and thus the birth of the “atomic age”. Next Becquerel’s investigations of these mysterious rays led to his experiments with uranium salt crystals. He th...

The Radiation of Ionizan Rays in the Treatment of.Benign Diiseases

SUMMARY In the early days of the discovery of X-rays, it was widely used in the treatment of benign diseases such as some chronic infections and chronic skin conditions, however, with better recognition of side effects specially carcinogenecity of the radiation, their use in benign diseases are now restricted only to a few of non-malignant conditions, when all else has failed, and with the kno...

An arrangement for irradiating cultured mammalian cells with aluminium characteristic ultrasoft x-rays.

Ultrasoft x-rays are useful for testing the validity of mechanistic models of biological damage caused by radiation. Described here is the construction and operation of a cold-cathode transmission-target discharge tube for irradiating mammalian cells in vitro with aluminium characteristic x-rays (1.487 keV). Particular attention is given to the problems of sample preparation and dosimetry for t...

Affinity Labeling of Membrane Receptors Using Tissue-Penetrating Radiations

Photoaffinity labeling, a useful in vivo biochemical tool, is limited when applied in vivo because of the poor tissue penetration by ultraviolet (UV) photons. This study investigates affinity labeling using tissue-penetrating radiation to overcome the tissue attenuation and irreversibly label membrane receptor proteins. Using X-ray (115 kVp) at low doses (<50 cGy or Rad), specific and irreversi...
