RESUMEN
We present a collimator configuration for measuring energy resolved x-ray plasma volume bremsstrahlung emitted, e.g., by an ECRIS. Special attention we paid to shielding the detector against interfering Compton scattered radiation and wall bremsstrahlung stemming from the collimator entrance aperture. We estimate the efficiency for shielding of Compton scattered radiation at least attainable by this arrangement.
RESUMEN
It is evidence based that research involving children is really very important, and organizations involved in child health support this view. This importance is reflected both in political policy and international regulations. However risk in children's research is a difficult area; so potential benefits and harm to children at all stages of any research must be ensured. The expected risks should be kept as low as possible. Moreover issues such as rights to information inform consent and confidentiality of children must be protected and regulated by the law. The authors present overview of international regulations of children involving research, comparing analysis of Convention of Child Rights and Georgian legislation of minor patient's rights. Emphasis issues of rights to information, inform consent and confidentiality of children and adolescence in research according to international and Georgian regulations.
