The activity concentration of gross alpha and gross beta particles in four samples of borehole drinking water consumed in Ibrahim Badamasi Babangida University (IBBU), Lapai, Niger State-Nigeria was measured, using a portable single channel gas free proportional counter (MPC2000B-DP) detector. This study focused on cancer related problems and the bio-data of the environment was discussed as wel...

Background: The natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: The natural radioactivity levels (226Ra, 232Th and 40K) in the ceramic tiles were measured using high-purity germanium detector system (HPGe) and the related radiological hazards were assessed by radium equivalent activity (R...

Background: The activity concentrations of 226Ra, 232Th and 40K in sand used as building material in Weifang of China were investigated for evaluating the radiation hazard. Materials and Methods: Sand samples were collected from Weifang and their radioactivity levels were measured using gamma-ray spectrometry. The radiation hazard for residents was assessed by radium equivalent activity (Raeq),...

BACKGROUND Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. MATERIAL AND METHODS ...

The potential for biological, chemical, radiological, or nuclear terrorism has been widely acknowledged since the events of September 11, 2001. Terrorists' use of a radiological dispersal device (RDD), or dirty bomb, is considered to be a threat for which Americans must prepare. Occupational health nurses must have the knowledge and skill set to plan for, respond to, and recover from a radiolog...

abstract the genus aspergillus, which consists of a few hundred opportunistic mold species found in various climatic conditions, causes diseases including localized infections, fatal diseases, allergic responses, and inhaled conidia in humans. herein, we present an overview of the most common diseases and allergic infections caused by aspergillus species and their associated health hazards in v...
