For radiotherapy to be safe and effective a number of technical conditions have to be met to ensure that the radiation beam is appropriate for each individual patient and that the dosage received by the patient is as planned. While it is the function of the radiotherapist to decide the characteristics of the treatment, he may not have the technical background to ensure that the equipment is operated in such a way that the desired results are achieved. This responsibility belongs to the medical radiation physicist.

Recognizing the importance of accurate dosage in radiation therapy, the International Atomic Energy Agency initiated a progamme in dosimetry of ionizing radiations soon after its foundation. At that time neither national nor international absorbed dose standards existed, so a transportable absorbed dose calorimeter was designed and built in the Agency’s Laboratory as early as 1960. Being one of the first instruments of its type, this calorimeter was used for making absolute dose measurements and dose intercomparisons with other dose reference instruments. A few years later, the proposal was made to organize a dose intercomparison service by mail for radiations therapy departments.

Technologies that make use of radiation continue to spread around the world: millions of people are employed in radiation related occupations and hundreds of millions of people benefit from these applications. The use of intense radiation sources for purposes such as the sterilization of medical products requires special care in the design and operation of equipment to prevent radiation injury to workers or to the public. Experience has shown that such technology is generally safely used, but controls have on occasion been circumvented and serious radiological accidents have ensued.

To find out how consistent or variable is the understanding and practice of radiation protection procedures for women in the childbearing age at a multispecialty tertiary hospital. A questionnaire was distributed during grand rounds, mid-day clinics and a radiology conference. Questions included which radiation protection rule does the respondent use for females, whether, he or she is familiar with those rules and what is his or her source of reference. Further questions were about the radiation dangers to the fetus. The understanding and practice of radiation protection guidelines for females is inconsistent. There is significant unfamiliarity with the radiation protection rules among our hospital practitioners.

In the light of a growing awareness of the risks of inducing skin injuries as a consequence of fluoroscopically guided interventional procedures, this paper compares three methods of monitoring entrance surface dose. It also reports measurements of ESDs made during the period August 1998 to June 1999 on 137 patients undergoing cardiac, neurological and general FGIPs. Although the sample is small, the results reinforce the need for routine assessment would seem to be arrays of TLDs. However, transducer based methods, although likely to be less accurate, have considerable advantages in relation to a continuous monitoring programme. It is also suggested that there may be the potential locally for threshold dose area product values to be set for specific procedures. These could be used to provide early warning of the potential for skin injuries.

The biodistribution of radiopharmaceuticals may be modified by drug interaction. Unknowledge of such factor can induce a poor misvisualization of the scintigraphy images, leading to the repetition of the examination, increasing the radiation dose for the patient. We are trying to develop a model to evaluate the influence of drugs on the biodistribution of radiopharmaceuticals. Mitomycin-C is a drug that has been used as a component of many chemotherapeutic regimens. We have studied the effect of mitomycin-C on the biodistribution of the pyrophosphate labeled with technetium-99m. These results can be justified by the metabolic process and/or the therapeutical effect of mitomycin-C and this alteration on the biodistribution of the studied radiopharmaceutical was capable to increase the radiation dose in some organs.
