We consider the problem of finding the localization of radioactive source by using data from a digital camera. In other words, the camera could help us to detect the direction of radioactive rays radiation. Therefore, the outcome could be used to command a robot to move toward the true direction to achieve the source. The process of camera data is performed by using image processing and computa...

in the recent years, interstitial brachytherapy implantation has become the treatment of choice for early stage prostate cancer patients. treatment of prostate cancer with radiation is traced back to 1909. originally this treatment modality was very crude and could not gain much popularity till 1982. advancements in radioactive source designs, introduction of new low energy radioactive sources,...

The physical protection of nuclear material and nuclear facilities is a highly mature field, dating virtually from the inception of the nuclear age, with longstanding international requirements and guidance. While the international community, including both the IAEA and Member States, has achieved much progress within the decade since approval of the Code of Conduct, the security of radioactive...

This paper compares the accuracy of imaging and resolution obtained with 81Rb and 43K using coincidence and noncoincidence counting. Phantoms and isolated infarcted dog hearts were used. The results clearly show the superiority of coincidence counting with a resolution of 0.5 cm. Noncoincidence counting failed to reveal even sizable defects in the radioactive source.

Background: The Ural region is highlighted among other Russian regions for its unfavorable radiation situation and complexity of the overall environmental situation. The source of man-made radioactive contamination is the work of the "Mayak" Production Association. A significant radioactive contamination has happened as a result of several radiation incidents in the early period ...

A radioactive source is usually replaced and disposed after being used for a certain amount of time (usually a half-life). In this study, a simple method is proposed to prolong its service life. Instead of replacing the used source with a new source of full activity, a new source of less activity is added in the source holder in front of the used one, so that the total activity of two sources i...

For the first time, soil core samples from the Jiuquan region have been analyzed for Pu isotopes for radioactive source identification and radiological assessment. The Jiuquan region is in downwind from the Lop Nor Chinese nuclear test (CNT) site. The high Pu inventories (13 to 546 Bq/m(2)) in most of the sampling locations revealed that this region was heterogeneously contaminated by the regio...
