This study presents the results of ambient radioactive radiation, radiation health hazard indices and excess lifetime cancer risk estimation around radiological sections in Federal Teaching Hospital Gombe, Gombe State, Nigeria using a well calibrated Rados-200 meters Global Positioning System (Garmin 765). The mean annual outdoor equivalent dose 0.078 mSv/y. was measured. Mean effective doses 0...

To walk 100 meters at 4 kilometers per hour (an average walking pace) takes about 1.5 minutes. What would prevent an oncologist investing this brief time in visiting a patient in the next building? It is not that oncologists as a group are uncaring. I can think of too many examples where the opposite is true. Was he too busy? Was he burned out? Did he feel guilty at having failed to control the...

Ionizing radiation is one of the main risks affecting healthcare workers and patients worldwide. Special attention has to be paid to medical staff in the vicinity of radiological equipment or patients undergoing radioisotope procedures. To measure radiation values, traditional area meters are strategically placed in hospitals and personal dosimeters are worn by workers. However, important drawb...

A problem in accurately measuring regional myocardial blood flow by radiation washout techniques is the inability to localize precisely the origin of radiation in tissue. We developed a new approach for in vivo localization and quantification of regional blood flow. A miniature, silicon, solid-state, avalanche radiation detector, which measures the low-penetrating radiation from commonly availa...

A national survey comprising approximately 60% of all Canadian mammographic facilities was conducted in 1994-95. The survey, which was coordinated by Health Canada, was a cooperative undertaking of the federal and all provincial and territorial governments in Canada. The survey protocol, which was developed by the U.S. Food and Drug Administration (USFDA), was used for U.S. national surveys in ...

OBJECTIVE To document the ability of public health laboratories to respond to radiological emergencies. METHODS The Association of Public Health Laboratories developed, distributed, and analyzed two separate surveys of public health laboratories representing the 50 US states and major nonstate jurisdictions. The 2009 All-Hazards Laboratory Preparedness Survey examined overall laboratory capab...
