Activity concentrations of natural radionuclide levels in well waters of Ago Iwoye, Nigeria

Natural Radioactivity, though natural requires concentration monitoring, especially for the health/ environmental checks of the populace. The activity concentrations of 40K, 238U and 232Th in the waters from wells with depths ranging between 141.0 - 214.0 feet were randomly sampled and determined from 20 locations in Ago-Iwoye town in South Western, Nigeria. The activity concentrations obtained were in the ranges of [9.9-50.9]Bq/kg with mean value of [25.1 +/- 10.7] Bq/kg for 40K, [BDL-15.0] Bq/kg with mean value of [1.2 +/- 3.2] Bq/kg for 238U and [BDL-6.2] Bq/kg with mean value of [1.6 +/- 1.7] Bq/kg for 232Th. According to the results obtained for the activity concentrations from 20 well water samples in Ago Iwoye, Southwestern, Nigeria it was observed that the v40K, 238U and 232Th values were still within the tolerance level indicating minimal radiological health burden on the human populace and the environment

Effect of cycocel in the prevention of lodging in wheat [triticum aestivuni] with the application of nitrogen fertilizer

The effect of a plant growth regulator [retardant] -Cycocel [C.C.C.] and nitrogen on three varieties of wheat were studied under Jos-Plateau ecological condition. Pre-seeding treatments of the wheat seeds with Cycocel at three different concentrations [0, 250 and 500 ppm] and two levels of nitrogen [90 and 120 kg/ha] were carried out. There were significant reduction in plant [stem] height and internodal lengths at both levels of Cycocel treatments [250 and 500 ppm] and the two levels of N-fertilizer, on one hand. On the other hand, there were marked increase in stem girth at both levels of Cycocel treatments and the two levels of applied nitrogen. It is concluded that wheat varieties that are highly susceptible to lodging at optimum or fairly high N-fertilizer application can be corrected with Cycocel treatment resulting in wheat plants with sturdy and compact appearance
