a subject entirely beyond his comprehension and one that he must leave to the specialist. We are not suggesting that every practitioner should have a gramme or two of radium at his disposal to exper1' ment with, but he must understand something of the principles of its action and of its possibilities in the treatment of cancer, otherwise he will not be in. a position to advise his patients when...

abstract background: and soils with which it comes in contact. there is dual exposure from radon in water i.e. due toinhalation of the radon released from the water into the ambient air and through ingestion whenwater is used for drinking. as radon contaminated water adversely affects the health, it istherefore fundamental from health and hygiene point of view to measure radium concentrationand...

-Radium sorption efficiencies as a function of temperature, Ra concentration, and secondary mineral sorbate were determined in a 0.0! M NaC1 solution. Radium sorption on a characterized clinoptilolite, montmorillonite, nontronite, opal, silica gel, illite, kaolinite, and glauconite under comparable experimental conditions allowed determination of Ra sorption efficiency curves for each, through ...

background: natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. so, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. materials and methods: ...
