“…The total AED from the consumption of vegetables was 0.048 mSv, this is 16% of the recommended value of 0.3 mSv/y due to radionuclides of natural origin in all diet (UNSCEAR, 2000) further investigation is necessary. The ELCR obtained was 0:17 Â 10 À3 this is lower than the world's average value of 0:29 Â 10 À3 (Thabayneh & Jazzar, 2012). This value, however, implies that there is an added probability of 170 cancer incidence out of a population of one million due to consumption of leafy vegetables cultivated in Lagos metropolis.…”

In the industrialized area of Lagos, vegetables are mostly cultivated through surface water irrigation. Untreated surface water has the potential of being contaminated with radionuclides from industrial effluents. This study evaluated the concentration of radionuclides in the leafy vegetables cultivated through surface water irrigation in Lagos metropolis and the potential health risks associated with their consumption. The specific activities of 226 Ra, 232 Th and 40 K in some commonly consumed leafy vegetables were determined using High Purity Germanium (HPGe) detector. To assess the radiation hazards associated with the consumption of these vegetables, annual effective dose (AED) and excess lifetime cancer risk (ELCR) were also determined. The specific activities of 226 Ra, 232 Th and 40 K in the investigated samples ranged from 0.49±044 to 6.00±1.19 Bq/kg, with an average value of 2.08±0.59 Bq/ for 226 Ra, from 0.10±0.07 to 0.61±0.12 Bq/kg with an average value of 0.85 ±0.08 Bq/kg for 232 Th and from 28.69±3.09 to 126.71±5.86 Bq/kg with an average value of 72.56±5.36 Bq/kg for 40 K. The mean activities of 226 Ra and 232 Th were 40 and 56 times higher than the World Health Organization (WHO) reference values for 226 Ra and 232 Th in leafy vegetables respectively. The AED estimated from the consumption of vegetables was 0.048 mSv/y, which is about 16 % of the reference AED value for radionuclides of natural origin in the total diet while leafy vegetable represents about 8 % of the total diet of an adult in Lagos. The ELCR obtained from this study was this is lower than the world's average value. This study has found elevated concentrations of 226 Ra and 232 Th in leafy vegetables, and noticeable increase in AED associated with 226 Ra exposure in the consumption of leafy vegetables cultivated in Lagos. There are therefore potential radiological health risks to the health of the public from long-term consumption of leafy vegetables cultivated through surface water irrigation in Lagos, Nigeria.

The identification system for radioactive elements used the single-channel analyzer (SCA) gamma spectroscopy method. However, the process of producing the spectrum was still quite long because it had to go through the process manually by scanning its energy; one of the other radioactive elements is gamma spectroscopy. This research aims to develop a prototype gamma spectroscopy that allows the identification of radioactive elements. In this study, researchers used an experimental method by designing a gamma spectroscopy prototype consisting of a 2.5 cm diameter NaI(TL) detector equipped with a photomultiplier, high voltage module, preamp module, pulse shaping module, sample hold module, and Atmega microcontroller with an LCD display resolution of 128 × 64. The results of testing this prototype were carried out with various radioactive samples. Researchers managed to identify radioactive elements by measuring electrical pulses produced by NaI(TL) detectors. Background counting, which is the result of enumeration from detectors without radioactive material, was identified and eliminated. The distribution pattern has a random nature, the energy resolution of the spectroscopy consists of 1024 channels, and the counting time can be set as needed via the reset button. The main finding of the study was that the gamma spectroscopy prototype was able to provide a clear picture of the energy spectrum of nuclear radiation, allowing good identification of radioactive elements. The results of this study have important implications in the field of identification of radioactive elements and can be used in a variety of scientific and industrial applications involving nuclear radiation.

“…where A is the activity concentration of the radionuclide in Bq/kg, and for liquids in Bq/L, KC is the net count for each radionuclide which is the count minus the background (count per second), t is the counting lifetime in seconds, v is the volume of water in liter, m is the mass in kg, ɛ is the detector energy dependent efficiency for each radionuclide, and Pγ is gamma ray yield per disintegration of the nuclide (emission probability) [28,21].…”

In this study, we quantify specific activity of 238U, 232Th, and 40K, from soils, water, and vegetables around limestone mining sites because of the dense urban settlement with high agricultural activities around the area. Annual effective dose (AED) was evaluated and used to estimate radiological hazard impact. Mean values of internal radiation hazard index (Hin) for soils, water, and vegetation are calculated and compared with those from literatures. The estimated mean excess lifetime cancer risk (ELCR) was obtained, too. The values of ELCR are under the world average value as recommended by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) one of the world regulatory bodies. For this reason, health related issues may occur at long time of living in this environment.
