Naturally occurring radioactive material and naturally occurring mercury assessment of black powder in sales gas pipelines
Black powder solids are formed inside the sales gas pipelines as a result of internal corrosion due to condensed moisture and the presence of corrosive gases, namely, H2S, CO2, and O2. Naturally occurring radioactive material, principally the radionuclides lead-210 and polonium-210, and naturally occurring mercury (NOM) (Hg) have been identified in black powder. A detailed investigation into both the radiological components and the presence of NOM associated with black powder was carried out by Saudi Aramco. The aim of the investigation was to determine if waste produced during pipeline scraping operations presented a workers protection or environmental control problem due to the radioactivity and mercury present. The investigation looked at Saudi Aramco's entire sales gas pipeline network and spanned scraping operations over a 3-year period. This article details the sampling and analysis methods used to assess black powder samples, the results of sample analysis and advice provided to ensure workers' protection, and environmental control of the waste produced during pipeline scraping activities.

New Primary Leaders
New primary leaders face significant challenges worldwide and this book brings together the range of those experiences and challenges for the first time. It includes interviews with primary school leaders in the early years of leadership in 12 different countries. Each chapter begins with an introduction to the principal and the local context before the principal's own description of her or his experience as a new leader. The leaders discuss how they prepared for principalship, their experiences after taking up the post, the extent to which the job meets with their expectations and their hopes and fears for the future. The final chapter provides a comparative overview, exploring new principals' perceptions of key influences on schools and their communities, their reactions to the multiple, heightened and often-conflicting expectations, pressures and challenges they encounter and the implications for principal preparation internationally. The voices of principals from around the world provide a vivid and authentic picture of new school leaders in different contexts at the beginning of the 21st century.

\Being\ a new principal in Scotland
Purpose - This paper aims to explore the extent to which the programme for principal preparation in Scotland relates to what is expected of principals once they are in post and what it is that they actually do.Design methodology approach - The paper analyses the professional experience of five relatively new elementary school principals reported in monthly logs maintained over a six-month period.Findings - The preparation for headship programme appears to help develop the professional identity of aspiring headteachers, broaden their outlook and develop confidence and self-belief. What is not clear is the extent to which the programme is developing principals with the strength of purpose required to work towards schools centred on educational values.Originality value - The paper builds on previous work by the authors and makes a contribution to the research on principal preparation and the work of new school principals.
