SU-E-I-35: Experience with Th Zero Gravity Suit

Medical Physics
J Pierno, C Hamilton

Abstract

To compare the effectiveness of the Zero Gravity Suit (CFI Medical Solutions) in reducing the annual dose received by one physician in the Cardiac Catheterization Lab. A physician with a history of receiving high annual dose equivalents was purchased a Zero Gravity Suit. Film badges (Landauer) were worn at the collar and waist and monitored monthly. Previous dose history was acquired via the Landauer Exposure Report Archive. Annual values for Deep Dose Equivalent (DDE), Eye Dose Equivalent (LDE), and Shallow Dose Equivalent (SDE) were compared for the first full year of the Zero Gravity Suit (2011) to the previous four years (2007-2010). Readings for 2009 and 2007 were corrected for improper wear of the film badges. The reduction in dose equivalent for DDE ranged from 70%-87%. The reduction in dose equivalent for LDE ranged from 16%-60%. The reduction in dose equivalent for SDE ranged from 16%-60%. It was determined that the Zero Gravity Suit is effective at reducing the exposure of a physician with a history of high annual dose equivalents in our facilities Cardiac Catheterization Lab. While the suit did reduce the LDE and SDE it was more effective at reducing the DDE. During 2010 the suit was acquired midyear. The dose equiva...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
