This paper deals with the X-radiation from television receivers and video display terminals. The bremsstrahlung production rate was calculated according to the thick target theory, and the transmitted X-radiation was measured by the spectrometry method. The calculated and the measured results were compared and discussed. In addition, evidences were shown that only the highest energy component of the bremsstrahlung can penetrate the cathode ray tube.

Collection performance of a HEPA filter and a new type filter which was recently developed for removing fine particles below 0.3μm was verified by using a laser aerosol particle counter in the particle size range from 0.12 to 0.42μm diameter in which the filter performance was not sufficiently clarified. Tested filter sheets were 14.5cm by 14.5cm in dimensions.DOP particles ranging from 0.12 to 0.17μm exhibited higher penetration of HEPA filter than DOP particles from 0.27 to 0.42μm by a factor of 20 at the standard face velocity of 2.4cm/sec. The penetration of HEPA filter was 6.6×10-4 for 0.12 to 0.17μm DOP particles, and that of the new type filter was 3.1×10-6.It was confirmed that overall system penetration of two HEPA filters in series could be described as the product of each stage penetration.

In August 2018, the latest analysis of the UK National Registry for Radiation Workers (NRRW 3rd update) has been published. The NRRW studies have been published almost every ten years since the first analysis (1992). The series of NRRW aimed to analyse cancer risk from low dose occupational radiation exposure. This latest analysis is the study using third analysis data and an additional ten years of follow-up information, but did not include additionally dosimetry information. As the set of ten years lag period, only the risks of cancer were analysed, but excluding leukaemia risks owing to its lag period as two years. The same statistical methods were used in the series of NRRW study. This review provides an outline and summary of the key points of NRRW 3rd update. We denote introduction in chapter 1, summary in chapter 2, comparison with previous studies and other studies in chapter 3, discussion about results in chapter 4, meaning and limitation in chapter 5 and conclusion in chapter 6.

On 11 March 2011, a 9.0 magnitude earthquake, which occurred at Northern Japan, and subsequent tsunami caused serious damage to the Fukushima Daiichi Nuclear Power Station (FDNPS). People living within a radius of 30 km were evacuated from their homes. Residents of Namie Town stayed for several days at a location 30 km northwest of the FDNPS. However, as a highly concentrated radioactive plume passed over this location, the evacuees are very much worried about their radiation exposure. On the other hand, there are several nuclear facilities in Aomori Prefecture. Such circumstances may produce concerns among people regarding an increased risk of cancer or other radiation-induced disease. In this study, focusing on the citizens of Namie Town and Aomori Prefecture (Hirosaki, Aomori and Hachinohe Cities), their understanding of basic knowledge on radiation was investigated through anonymous questionnaires. The present study has revealed that people recognized that they are exposed to natural radiation of more than 1 mSv, Despite this fact, however, people in Namie Town believe even radiation of 1 mSv will cause them some biological effects. Although basic general knowledge on radiation should be provided, a reliable relationship between the general public and experts also needs to be established.
