Investigation and calculation of electron and photon absorbed dose to organs from Radon-222 and its progeny
Radon ( ) and its progeny is the main source of radioactivity in the environment. They enter the respiratory system after inhalation. The investigations indicated that Radon is the second cause for lung cancer.
The main source of is (half...
Evaluation of Radiation dose from Radon Ingestion and Inhalation in Water Suplies od Sadatshar and Javaherdeh in Iran
Evaluation of Radiation dose from Radon Ingestion and Inhalation in Water Suplies od Sadatshar and Javaherdeh in Iran...
Radon and radium concentrations in 120 samples of drinking springs and rivers water sources of northwest regions of Mashhad
Radon makes up approximately half of the total dose of radiation were received naturally. The majority
of it comes from the inhalation of progeny of 222Rn and is prominent in a closed atmosphere. The
continuous measurement...
Radon transfer from water to milk
Radon, as naturally occurring radioactive gas, is responsible for 50% of the total background radiations in
human.
Radon gas is able to enter to human body through eating and drinking. So
,
measurement of received radiation in

Radon and Radium Measurement in Water Supplies of Sadatshahr and Javaherdeh Regions in Iran
Radon is a naturally occurring radioactive gas
that is emitted from soils and rocks and is in some water
sources. Radon is estimated to cause many thousands of
deaths each year. That's because when humans breathe air...
Evaluation of the Radiation Dose from Radon Ingestion and Inhalation in Springs, Wells, Rivers and Drinking Water of Ramsar in Iran
major contribution to the public exposure
on Earth has the natural radioactive element Radon (Rn-
222). There is a risk of developing cancer from long term
exposure to radon in air and water. The inhalation of
radon, a...
Segmentation of Blood Vessels in Fundus Color Images by Radon
In this paper we have presented an algorithm
for vessel detection in retinal color images which works based
on local Radon transform and morphological reconstruction.
In our previous work, the algorithm was applied to...
Estimation of gamma organ doses due to Radon-222 progeny in ORNL phantom
The most important source of natural radioactivity is Radon-222 For this reason, Radon dosimetry has
attracted quite a lot of attention which resulted in a vast number of research activities carried out in scientific communities by scientists...
On the inverse of the directional derivative operator in RN
to straight line propagation of radiation emitted by the spatial source distribution ρ. In particular, we examine the special two-dimensional case to point out the connection with the classical Radon transform. We then show how the Radon transform inversion...
