NATION WIDE Rn AND Rn ATLAS FOR INDIA
Considering the epidemiological effect of radon on human beings, an attempt is made to make a nation-wide atlas of Rn and Rn for India. More than 5000 measurements have been carried out in 1500 dwellings across the country, India. The solid state nuclear track detectors were deployed for the measurement of indoor Rn, Rn and their progeny levels. The mean annual inhalation dose rate due to Rn, R...
متن کاملAPPLICATION OF NIST ^Rn EMANATION STANDARDS FOR CALIBRATING ^Rn MONITORS
Several years of research in developing a radon emanation standard by the National Institute of Standards and Technology (NIST) has led to NIST Radon Emanation Standard SRM 4968 (Journal of Research of the MST 100:629-639; 1996). This new standard is based on a polyethylene -encapsulated ""Ra solution that has been demonstrated to emanate a well-characterized and known quantity "̂Rn when employe...
متن کاملRn- and Gn-Logics
This paper proposes a simple, set-theoretic framework providing expressive typing, higher-order functions and initial models at the same time. Building upon Russell’s ramified theory of types, we develop the theory of R-logics, which are axiomatisable by an order-sorted equational Horn logic with a membership predicate, and of G-logics, that provide in addition partial functions. The latter are...
متن کاملTranscendental submanifolds of Rn
In this paper we show how the restriction of the complex algebraic cycles to real part of a complex algebraic set îs related to the real algebraic cycles of the real part As a corollary we give examples of smooth submanifolds of a Euchdean space which can not be isotoped to real parts of complex nonsingular subvaneties in the corresponding projective space Algebraic numbers are dense in R. The ...
متن کامل^rn Progeny Surface Deposition
The radiological hazard of radon gas to occupants in residential environments is from the particulate progeny "'Po, ""Pb, ^Bi and "4P0, rather than ^Rn itself. Attachment to aerosols, plateout and resuspension impacts on the actual progeny airborne concentrations. Plateout rate factors are measured for different air change (ventilation) rates, ACH, in a 0.28 m3 test chamber for interior residen...
