This study we tried to investigate the effect of Cobalt radiation in lung of Wistar rats weighing 160 to 180 gr. A total of 60 rats were divided into 4 groups with 15 rats each.T1, First group as control group did not receive any radiation, T2) was irradiated with 5 Gy, T3) was irradiated with 7.5 Gy, T4) ws irradiated with 12 Gy. These findings demonstrate dosage d.ependent changes in differen...

Samples ( 1 and 5 liters) of filtered seawater (0.5 Jo) at its natural pH were equilibrated with several ,Gi of either carrier-free zinc-65 or carrier-free cobalt-60 and allowed to flow down individual resin columns. Retention of the ions was estimated by examining the eluate for activity; both cobalt and zinc were completely retained by the resin from both the 1 and 5 liter samples of seawater.

A considerable amount of work has been reported in the literature on the effect of x-rays on antibody formation and immunity. With the exception of the reports from our laboratory,5"' the depressing effect of cobalt-60 gamma radiation upon immunity and antibody formation has not been reported. It would seem logical that x-rays and gamma rays should have a similar physiological effect. However, ...

BACKGROUND Radiation-therapy is a complex process with multiple steps, each of which has an impact on the quality of treatment. Accurate dosimetry is a critical step during the radiotherapy of cancer patients.The aim of the present study was to measure and evaluate the doses of two cobalt- 60 (60Co) teletherapy units GWXJ80 of NPIC China and Theratron 780 of AECL Canada at various points within...

Human cancer is probably as old as the human race. For normal cells, the growth, division and death of cells occur in a controlled manner. Cancer cells on the other hand multiply in an uncontrolled way creating tumors. Tumors may replace healthy tissues and often start spreading to other parts of the body, leading to a lifethreatening situation. If untreated, most cancers lead to protracted suf...

By a direct-liquid-evaporation chemical vapor deposition (DLE-CVD) method, we deposited smooth lowresistance cobalt (Co) and cobalt nitride (CoxN) thin films with excellent conformality at low temperatures down to 200 1C. In the DLE process, a cobalt amidinate precursor solution, bis(N,N0-diisopropylacetamidinato)cobalt(II) dissolved in tetradecane, was vaporized as it flowed smoothly, without ...

AIMS To investigate whether exposure to cobalt in cobalt plants has any measurable effect on the cardiovascular system. METHODS Occupational, cross sectional study, using a self administered questionnaire, blood pressure measurement, electrocardiography, and laboratory tests in which 203 male workers with at least one year of exposure to cobalt and 94 unexposed controls participated. Echocard...

Cobalt sulfate was recovered from crushed and screened prismatic type spent lithium ion batteries (LIBs) containing 5~20 % Co, 5~7 % Li, 5~10 % Ni, 15% organic chemicals, and 7% plastics together with Cu, Al, Fe, and Mn. Cobalt was reductively leached from the -16 mesh fraction in 1 h by stirring with 2 M H2SO4 and 6 vol% H2O2, at 60 C and 300 rpm using a solid/liquid ratio of 100 g/L to give a...
