Primordial Radioactivity and Prebiotic Chemical Evolution: Effect of γ Radiation on Formamide-based Synthesis.

Journal of Physical Chemistry B, 2020
Although the effect of ionising radiation on prebiotic chemistry is often overlooked, primordial natural radioactivity might have been an important source of energy for various chemical transformations.

Radioactive Substances

1980
The purpose of this chapter is to show how to assess the detriment resulting from the release of radioactive materials to the environment. Because of the wide range of the subject and the limitation of space the chapter consists of little more than a listing of principles and concepts.

Pathways of Radioactive Substances in the Environment

2011
The release and transport of radionuclides in the environment is a subject of great public concern. The primary sources of radionuclides in the environment are nuclear weapons testing and production, and the processes associated with the nuclear fuel cycle.

Three-dimensional localization and radioactivity quantification of radiation sources through inverse estimation based on Compton camera measurements.

Radiation Protection Dosimetry
To minimize the radiation exposure of workers and plan effective remediation strategies at the decommissioning site of the Fukushima Daiichi Nuclear Power Station, accurately locating radioactive substances is extremely important. Accordingly, this study

The Radioactive Substances Act 1960

The Annals of Occupational Hygiene, 1964
The Hadioactive Substances Act 1960 that came into effect on December 1, 1963 requires persons who keep and use radioactive material to be registered with the Ministry of Housing and Local Government, and to obtain authorization for the accumulation and/or disposal of radioactive waste.

Exploring the alteration of environmental radioactivity in terms of compositional elements of heavy minerals in an anthropogenically affected urban river: Radiological and ecological risks assessment.

Marine Pollution Bulletin
This study explored the alteration of naturally occurring radioactive materials (NORMs: 226Ra (≈238U), 232Th, 40K) in an anthropogenically disrupted urban river-basin (Turag, Bangladesh) in terms of constitutional substances (Sc, Ti, V, Fe, La, Ce, Sm ...

Control of radioactive substances

2015
The possession, use, transport, and disposal of radioactive materials are controlled through regulation to limit exposure of the public and workers. This chapter describes the methodologies employed. Regulation is enacted through a system of notification and licensing, based upon recommendations from the IAEA and ICRP.

Shipping radioactive substances

Physics Today, 1949
In 1936, the manager of a film processing station in Chicago noticed periodic density variations occuring in rolls of 16-mm film sent in by mail for processing. The possibility that these rolls had been irradiated by unprotected shipments of medical radium or radon in the mails was suspected, and inquiry at the Chicago Post Office proved this to be the
