Cancer and the radiotherapist.
THE first cure of skin cancer with ionizing irradiation was reported in I899. Within a few years the new rays had been tried out on many disease processes, including deep tumours. Cures of superficial, accessible cancers were reported in increasing numbers, but at the same time complications followed the use of the new rays. These included the production of cancer. By the 1930s radium and radon...
متن کاملProton Radiobiology
In addition to the physical advantages (Bragg peak), the use of charged particles in cancer therapy can be associated with distinct biological effects compared to X-rays. While heavy ions (densely ionizing radiation) are known to have an energy- and charge-dependent increased Relative Biological Effectiveness (RBE), protons should not be very different from sparsely ionizing photons. A slightly...
متن کاملthe tragedy of modern man in arthur millers world
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...

متن کاملFast-neutron radiobiology and radiotherapy.
The application of fast neutrons, negative pions or heavy ions will only provide an advantage for the radiotherapy of cancer if, in comparison with conventional radiations, e.g., X-rays, gamma rays and electrons, better depth-dose and collimation characteristics or specific radiobiological dose response relationships result in greater local control probabilities for tumours without increased fr...
