The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

ABSTRAKT

We performed a chromosomal aberration analysis on blood samples of 15 radiation workers by scoring dicentric aberrations. These workers were chronically exposed to cumulative doses of approximately 500 mSv over a period of two to three decades. The biological doses estimated using the linear coefficient of the in vitro dose/response curve based on dicentric frequency varied from 0 to 259 mGy, even though all the radiation workers had received approximately the same physical dose—i.e., 500 mSv. In all cases of chronic exposure, the estimated biological doses were found to be lower than the measured physical doses. The measured physical doses were corrected by applying the biphasic decay pattern of lymphocytes and also taking into consideration the time course of accumulation of doses in each individual. The corrected physical doses thus obtained were then compared with the estimated biological doses, and a reasonably good correlation was found between these two sets of values. However, on the whole, the corrected physical doses were found to be smaller than the estimated biological doses in most of the cases. This observation suggests that the kinetics of turnover of lymphocytes in conditions of chronic exposure may be slower than estimated so far in various studies involving exposures to high doses, wherein the estimation of life span of lymphocytes was carried out in patients undergoing radiotherapy.
