Data have been collected and physical and statistical models have been constructed to estimate unknown occupational radiation doses among 90,000 members of the U.S. Radiologic Technologists cohort who responded to a baseline questionnaire during the mid-1980s. Since the availability of radiation dose data differed by calendar period, different models were developed and applied for years worked ...

Background The objective of this study is to suggest revised recognition standards for occupational disease due to chromium (VI) by reflecting recent domestic and international research works and considering domestic exposure status with respect to target organs, exposure period, and cumulative exposure dose in relation to the chromium (VI)-induced occupational disease compensation. Methods I...

Abstract The International Commission on Radiological Protection has recently published a report (ICRP Publication 147; Ann. ICRP 50 , 2021) the use of dose quantities in radiological protection, under same authorship as this Memorandum. Here, we present brief summary main elements report. 147 consolidates and clarifies explanations provided 2007 Recommendations (Publication 103) but reaches co...

ABSTRACT Introduction: Vaccination remains a key strategy to living endemically with COVID-19. The Pfizer-BioNTech COVID-19 vaccine was first granted interim authorisation for use in Singapore December 2020. With overseas studies published about the safety and side effect profiles of mRNA vaccines focusing mainly on non-Asian populations, we described effects vaccination experienced by healthca...

BACKGROUND Radiation, which is used extensively to diagnose and treat human diseases, poses an occupational health risk for the concerned health workers. Personal dosimetry is an important tool to monitor occupational radiation exposures. OBJECTIVE This study was conducted to reveal and to describe the situation of occupational radiation exposure monitoring among staffs in different health ca...

In a large case-control study (n = 1,926) of spontaneous abortion (SAB), exposure to solvents was ascertained by a telephone interview that asked about occupational use of 18 specific solvents or products, as well as an open-ended "other" solvent category. The adjusted odds ratio for use of any solvent was 1.1 (0.8, 1.5). Solvents for which at least a doubled crude risk of SAB was found include...

OBJECTIVE To examine the quantitative relation between exposure to isocyanates and occupational asthma, and to explore the role of atopy and smoking in occurrence of the disease. METHOD A case-referent study was undertaken of cases from two manufacturing companies (A and B) from which referents without disease could be selected and reliable exposure measurements were available. In company A, ...
