Air Kerma Strength Measurement Using a Seven-Distance Ionization Technique and Comparison With the Gamma Spectroscopy Method

Air Kerma Strength Measurement of a Cs-137 Radioisotope Using a Seven-Distance Ionization Technique and Comparison with the Gamma Spectroscopy Method

Brachytherapy describes a process where radioactive sources are inserted directly into the target area of a patient to treat disease. Before they can be used for treatment, brachytherapy sources must be calibrated such that medical physicists know their exact air kerma strength a quantity given by manufacturers as a standard. Each individual source must be measured before use. Therefore, medica...

Absolute Air-kerma Measurement in a Synchrotron Radiation Beam by Ionization Free-air Chamber

A dosimetric procedure to assure the traceability to the air-kerma standard of the measurements performed in synchrotron radiation beams, was implemented at the “Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti” of ENEA (INMRI-ENEA). To this purpose, absolute air-kerma measurements by the ENEA standard free-air chamber for low energy x-rays have been performed at the SYRMEP (SYnchro...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
