Background and objective: Children have a higher risk of being exposed to medication errors and are more prone to harm due to reasons such as differences in their growth and development, and their physiological and psychological characteristics which are different from those of adults. The purpose of this study is to determine pediatric nurses’ attitudes towards reporting of medication errors and causes of not reporting of medication errors and to determine their views on the incidence of medication errors.Methods: The study was conducted in a Children’s Hospital in the province of Izmir, with the participation of 179 pediatric nurses. To collect the data, two forms were used in the study, socio-demographic questionnaire and Questionnaire for Medication Errors.Results: While 34.6% (n = 62) of the nurses thought that medication errors never happened in the clinics over the past year. While 94.4% (n = 169) of the participating nurses did not report any medication errors within the past year, 5.6% reported 1-2 times. The highest proportion (75.4%) (n = 135) of the nurses, the reason for not reporting medication errors was the fear of receiving legal punishment.Conclusions: Reporting medication errors is low level. In conclusion, the main reason for not reporting medication errors was the perception of receiving punishment. Implications for nursing and/or health policy: Education to nurses should be given at regular intervals and in small groups by using case samples. If the managers are to promote reporting, they should eliminate the perception of receiving punishment, and make necessary arrangements to develop non-accusatory culture aiming to learn from the results of reported errors.

Effect of Gamma Radiation on Growth and Development of Rust Red Flour BeetleTribolium Castaneum(Herbst.)Study on the sterilizing and lethal effects of Cobalt-60 gamma radiation on the larval and adult stages of rust red flour beetleTribolium castaneum(Herbst.) was done at 0, 10, 30, 50, 70, 100, 150, 300 and 500 gray (Gy). Irradiation severely affected pupal period, pupal formation and survivability of larvae and adults. The developmental period of the pest was found to increase along with the increase in the radiation doses. The irradiation at 70 Gy was found to cause complete sterility in the insect.

Radiation Profile

Nuclear waste management facilities at Chalk River Laboratories (CRL) use below-ground “tile-holes” to store solid waste from various activities such as medical isotope production. After long periods of isotopic decay, some of the waste has decayed down to low activities and can be transferred to low-level waste storage facilities. This paper presents a method to verify the radiation level of the waste inside tile-holes by performing gamma radiation scans along the depth of waste storage tile-holes. Such measurements allow for noninvasive verification of tile-hole contents and provide input to the assessment of radiological risk associated with removal of the waste. Using the radiation profile system, the radiation level of the radioactive waste may be identified based on the radiation profile. This information will support planning for possible transfer of this waste to a licensed waste storage facility designed for low-level waste, thus freeing storage space for possible tile-hole re-use for more highly radioactive waste. CRL-developed small diode-based gamma radiation sensors have been used in these radiation scans. The diode sensors were deployed into verification tubes adjacent to the tile-holes to measure the radiation profile. Over 10 tile-holes have been scanned using this technique since 2009.

INTRODUCTION: Health promotion of infancy is necessary for the optimum growth and development. Mother is significant person for the promotion of health of infant. MATERIAL AND METHODS: Descriptive cross-sectional study was conducted to find out the awareness regarding health promotion of infants among 78 mothers in Bhim Hospital of Siddharthanagar Municipality by using purposive sampling technique. Semi- structured interview schedule was used to collect data and analyzed by using descriptive and inferential statistics with SPSS version 20. RESULTS: The study findings revealed that 51.3% of the respondents have low level of awareness regarding health promotion of an infant. There was statistically significant association between respondents’ level of awareness with occupation and respondents’ husband’s age. CONCLUSION: The study concluded that more than half of the mothers have low level of the awareness regarding health promotion of the infant. Mothers’ occupation and husbands’ age are the influencing factors on mothers' knowledge regarding health promotion of infant.

A recent broad study of the background of all types of low-level beta and gamma detectors has now made it possible to analyze its components more reliably and with greater detail. This general analysis is developed further here for gas proportional and liquid scintillation counters used in radiocarbon dating. The background of gas counters, which is dominated by secondary cosmic gamma radiation, is now well understood and can be described quantitatively. The background of liquid counters is less well understood and can only be described semiquantitatively, its analysis resting partly on estimates. Methods to reduce the background of both types of systems are described and their effectiveness discussed. This analysis may help in evaluating the quality of existing systems as well as in designing better ones.
