Does short-term exposure to elevated levels of natural gamma radiation in Ramsar cause oxidative stress?

Background: Ramsar, a city in northern Iran, has areas with some of the highest recorded levels of natural radiation among inhabited areas measured on the earth.

Aims: To determine whether short-term exposure to extremely high levels of natural radiation induce oxidative stress.

Materials And Methods: In this study, 53 Wistar rats were randomly divided into five groups of 10-12 animals.

The highest background radiation school in the world and the health status of its students and their offspring.

Although the average effective human dose from natural background radiation is about 2.4 mSv per year, the students of the Saeid Nafisi school in Ramsar received effective doses of about 250 mSv while studying there for over 5 years. The goal of this project was a retrospective study of the health status of former students of this school and their offspring.

CoolClot, a novel hemostatic agent for controlling life-threatening arterial bleeding.

Background: Uncontrolled bleeding is the first leading cause of preventable death in the battlefield and the 2nd cause of mortality in civil accidents. Incompressible hemorrhage control is among the interventions that drastically increase the survival rate in wound individuals. We have previously shown that a certain mixture of bentonite and zeolite minerals can significantly decrease the bleeding in rats.

High-performance heavy concrete as a multi-purpose shield.

Concrete has long been used as a shield against high-energy photons and neutrons. In this study, colemanite and galena minerals (CoGa) were used for the production of an economical high-performance heavy concrete. To measure the gamma radiation attenuation of the CoGa concrete samples, they were exposed to a narrow beam of gamma rays emitted from a (60)Co radiotherapy unit.

Development of a novel mineral based haemostatic agent consisting of a combination of bentonite and zeolite minerals.

Background: Haemorrhage remains the greatest threat to life on the battlefield, accounting for half of all deaths. Over the past decade the US army has widely studied new technologies for stopping sever haemorrhages and has introduced an effective zeolite based haemostatic agent. In this paper the bio-stimulatory effect of burned radioactive lantern mantles powder as well as two minerals; bentonite and zeolite are presented.
