    In this research, radon concentrations in surface water samples were measured at 8 stations and along 8 boat survey routes in the lower Nam Phong River, Khon Kaen Province, Thailand, using the RAD 7 Radon Detector and RAD AQUA accessories. The results of radon concentration at the 8 stations along the Nam Phong River ranged from 0.16 to 4.87 Bq/L, with an average of 1.17 Bq/L. For the boat survey routes along the Nam Phong River, radon concentrations ranged from 0.04247 to 0.12342 Bq/L, with an average of 0.07422 Bq/L. These results were lower than the maximum contaminant level of radon in water (MCL), 11.1 Bq/L, as the United States Environmental Protection Agency recommended. Finally, the results were used to assess various health risks to people in this research area, contributing to determining the public safety of radon exposure in the lower Nam Phong River.

    Abstract Assessment of annual effective dose due to inhalation (Dinh) and ingestion (Ding) of radon from 43 groundwater samples at Kantharawichai District, Maha Sarakham Province using Radon Gas Monitor ATMOS 12 DPX. The results were as follows: 1. radon concentrations ranged from 1.04 – 21.87 Bq/L with a mean of 8.26±3.77 Bq/L, 2. The Dinh ranged from 2.60 – 54.69 μSv/y with a mean of 20.70±9.40 μSv/y. The Ding ranged from 0.19 – 3.94 μSv/y with a mean of 1.50±0.70 μSv/y, 3. The annual effective dose on organs, namely the dose on lungs (Dlung) ranged from 6.26 – 131.24 μSv/y with a mean of 49.60±22.70 μSv/y, and the dose for stomach (Dstomach) is 0.45 – 9.45 μSv/y with a mean of 3.60±1.60 μSv/y, and 4. The mean of excess lifetime cancer risk (ELCR×10-4) in males was 0.90±0.40 and in females, it was 0.96±0.44. The results will be compared with the action levels of various organizations, including. The maximum allowable radon concentration in water is 11.1 Bq/L, according to US EPA, and the allowable annual effective dose is 100 μSv/y, in accordance with WHO. Analysis of results can signify the health safety of radon inhalation and ingestion of groundwater from the study area.

    AbstractAim of this research is a hazards assessment of radon concentration and effective radium content were estimated in 24 vegetables and 9 fruits samples that were collected randomly from local markets in Muang Nakhon Phanom Municipality, Thailand by active detecting method (RAD 7). The results showed that radon concentrations in vegetables were in the range of 6.27 – 45.11 Bq/m3, the mean was 21.32±2.36 Bq/m3and radon concentrations in fruits were in the range of 12.11 – 53.19 Bq/m3, the mean was 27.47±2.81 Bq/m3, respectively. All values of radon concentrations for vegetable and fruits in these study were found to be well below than the international standard level of radon concentration 190 Bq/m3recommended by the EPA. These results were also used to calculate the average effective dose equivalent (EDE) of radium from vegetables and fruits, calculation was 0.034 µSv/y, this is lower than the effective dose equivalent for the standard value of 1.3 mSv/y recommended by the EPA. This study show that vegetables and fruits were found to be safe from radon contamination.

  • Design and simulation of a low-energy single ion irradiation system for micro/nano-biosample investigation

    Abstract A low-energy single ion irradiation system is developed in its initiation in Thailand to follow one of the trends in novel ion beam technology exploitation. Single ion irradiation of materials is a highly technological development of ion beam technology. The developed single ion irradiation systems worldwide are primarily in the MeV-energy range and for single cell studies, and recently the trend has been extended to the low-energy range (< 100 keV) but focused on microelectronic applications. Based on our previous research on low-energy ion beam irradiation of biological cells and DNA, we design and simulate a low-energy single ion implantation system, aiming at eventual construction of such a novel ion beam apparatus for applications to the biological studies. In the system, the ion energy is decreased to orders < 1 keV by the existing deceleration lens, then the low-energy ion beam passes through µm slits, and finally, low-energy single ions are obtained by beam scanning with appropriate frequencies from scanner plates and detected by a single ion detection device. Conceptual design, calculation and simulation of this single ion system are presented.
