The gamma dosimetric response of the Methylene Blue (MB) in Polyvinyl Alcohol (PVA) films was investigated. spectrophotometric analysis done to observe changes these at pre and post irradiation. PVA based were irradiated using Cs137 γ-source within dose range (100-200) kGy. effect concentration dyes, pH dyed solutions thickness employed as parameters this study. stability MB-PVA before after ir...

Gamma irradiation device using Cs-137 have been widely utilized to the irradiation of cell, blood, and animal, and the dose measurement and education. The Gammacell 3000 Elan (Nordion International, Kanata, Ontario, Canada) irradiator was installed in 2003 with Cs-137 and dose rate of 3.2 Gy/min. And the BioBeam 8000 (Gamma-Service Medical GmbH, Leipzig, Germany) irradiator was installed in 200...

In April 2020, several wildfires took place in and around the Chernobyl exclusion zone. These fires reintroduced radioactive particles deposited during 1986 disaster into atmosphere, causing concern about a possible radiation hazard. Several countries stations of International Monitoring System measured increased Cs137 levels. This study presents analyses made by RIVM SCK CEN/RMI 2020 wildfires...
