Radiochromic film dosimetry in water phantoms [PDF]

Physics in Medicine and Biology, 2000
Radiochromic film is investigated for use in dosimetry in water phantoms as opposed to solid phantoms. Investigations are performed to measure the penetration rates of water into radiochromic film and to assess the effects on optical density that this penetration causes.

High sensitivity radiochromic film dose comparisons [PDF]

Physics in Medicine and Biology, 2002
This short note investigates the dose characteristics of a relatively new high sensitivity radiochromic film (Gafchromic HS) and compares dose and energy response to various Gafchromic film types and radiographic (EDR-2) film. The original MD-55-1 and two improved sensitivity films, MD-55-2 and HS film, were investigated for energy and dose response ...

Real-time dosimetry with radiochromic films [PDF]

Scientific Reports, 2019
AbstractRadiochromic film dosimetry has been widely employed in most of the applications of radiation physics for over twenty years. This is due to a number of appealing features of radiochromic films, such as reliability, accuracy, ease of use and cost. However, current radiochromic film reading techniques, based on the use of commercial densitometers

Dosimetry in CR mammography using radiochromic film

Brazilian Journal of Radiation Sciences, 2022
To estimate the dose that a patient's mammary tissue receives during mammographic screening, radiochromic film and objects simulators made of PMMA are used. This material interacts with X-rays in a similar way to tissue. Estimating the dose absorbed by a

放射線エネルギーの違いによる喉頭癌における吸収線量の影響 [PDF]

, 2002
We investigated the usefulness of Gafchromic MD-55 film (Nuclear Associates, Inc.) for measuring the radiation doses on the radiotherapy of laryngeal cancers. Since larynx has thin wedge-shaped structure in anterior neck adjacent to airway, the radiation
