Bronchial dosimeter for radon progeny.
A true bronchial dosimeter has been designed, consisting of four 400-mesh wire screens and a filter paper. With a face velocity of 3.3 cm s(-1) for home exposure and 4.6 cm s(-1) for mine exposure, the deposition pattern on the wire screens were found to satisfactorily match the variation of the dose conversion factor (in units of mSv WL M(-1)) with the size of radon progeny from 1 to 1000 nm. ...
متن کاملAssessment of radon gas using passive dosimeter in Amman and Al-Rusaifa cities, Jordan
Background: Radon concentration was measured in the soil and indoor of Amman and Al- Rusaifa cities in Jordan during summer season. Materials and Methods: The measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as CR-39. Results: Radon concentration levels in the soil ranged from 2.8 ± 1...
متن کاملDeveloping an integrating biological dosimeter for spaceflight
A major safety concern of human activities in outer-space is the exposure to harmful radiation in the environment. It is well known that radiation can induce mutational damage which can result in diseases such as cancer, and death due to radiation poisoning. Much of our understanding of the effect of radiation on living animals comes from genetic analysis of model organisms. As a well-establish...
متن کاملAn Improved WAGNER-WHITIN Algorithm
We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...
متن کاملAn improved constant-time algorithm for computing the Radon and Hough transforms on a reconfigurable mesh
The Hough transform is an important problem in image processing and computer vision. Recently, an efficient algorithm for computing the Hough transform has been proposed on a reconfigurable array [12]. For a problem with an p N p N image and an n n parameter space, the algorithm runs in a constant time on a threedimensional (3-D) n n N reconfigurable mesh where the data bus is N1=c-bit wide. To...
