Forest fires are annual problem during the dry season and become a biggest threat to forest resources in Indonesia. The forest fires release into the atmosphere large quantities of particulate matter and volatilized substances. The present study investigates effects of forest fire on air quality in the case of a radiological event of ashes from forest fires emissionsin Riau province during an intense forest fire season that occurred in 2015.Atmospheric aerosol samples were collected from Mayto December, 2015 using a large volume TSP (total suspended particles) sampler.Concentrations of radionuclidesin airborne particulate matter were measured by using gamma spectrometry.It was shown that the activity concentrations of 226Ra, 232Th and 40K ranged from 0.026 to 0.114 mBq/m3, 0.005 to 0.011 mBq/m3 and 0.99 to 5.64 mBq/m3, respectively. The activity concentrations of 137Cs in air was found lower than the minimum detectable activity of the gamma counting systems (<MDA), except for July and September 2015. The result showed that the smokefrom forest fires contain radioactive particulates, which may have a potential health risk of population, and need to be considered in forest fire disaster. Inhaled smoke particles from forest fires may contribute to enhanced radiation doses to the general public.

The yields of species such as e-aq, H•, •OH, H2 and H2O2, formed from the radiolysis of neutral liquid water by the incidence of 0.8-MeV neutrons at temperatures between 25 and 350°C, were calculated by using Monte Carlo simulations. The slowing down of these neutrons through elastic scattering produced recoil protons elastically of ~0.5057, 0.186, and 0.0684 MeV which had linear energy transfers (LETs) of ~40, 67 and 76 keV/µm, respectively, at 25°C. The effects of neutron radiation can be predicted based on the contribution of those first three recoil protons by neglecting the radiation effects due to oxygen ion recoils. Then, the fast neutron yields could be estimated by summing the yields of contributing protons after corresponding weightings were used according to their energy. In this work, yields were calculated at 10-7 and 10-6 s after incidence of neutron radiation in water at the aforementioned temperature range. Overall, there is a reasonably good agreement between our calculated and existing experimental G-values for the entire temperature range. However, we proposed an hypothesis that the not very significant difference between experimental data and our calculated data is due to the different measuring time used in obtaining the experimental data as compared to the ones used in our calculation. Our computed yields for 0.8-MeV fast neutron radiation show an essentially similar temperature dependences over the range of temperature studied with 2-MeV fast neutron and low-LET radiation, but with lower values for yields of free radicals and higher values for molecular yields.Received: 04 October 2014; Revised: 23 March 2016; Accepted: 23 March 2016

Ordered pores structureanalysis of mesoporous silica materials using a template of poly(ethylene oxyde)-poly(propylene oxide)-poly(ethylene oxide), PEO-PPO-PEO, triblock copolymer or Pluronics in numerous synthesis conditions has been conducted. Two different length of hydrophilic chain of Pluronics, i.e., P123 (EO20PO70EO20) and F127 (EO106PO70EO106), produced two different fine pore structures, which were basically hexagonal and cubic. A highly ordered pore structure, confirming with many Bragg peaks, was clearly obtained with the lattice parameters in nanometer scale from analyzing the synchrotron small angle X-ray scattering (SAXS) data. Meanwhile, the surface area and pores size of mesoporous silica determined by nitrogen absorption clearly support the analysis of SAXS data, presenting a complete information of pore order characteristics. This paper shows how the synthesis parameters,such as length of hydrophilic chains, silica precursor concentration, Al:Si ratio and synthesis methods, are related to the structure and order of the pores formed. The SAXS patterns show that the pore orderincreases with increasing concentration of sodium silicate and decreases with longer sonication time.

The present trend of global warming has led to an increase in seawater temperature and salinity. The effects of increasing salinity and temperature on the accumulation of 137Cs by milkfish Chanos chanos was studied under laboratory conditions to obtain information on Chanos chanos adaptability under environmental changes. The uptake of radioactive cesium by Chanos chanos increased with temperature of seawater. The concentration factors (CF) of 137Cs for temperatures of 25°C, 27°C, 29°C, and 31°C at steady state period were 5.25, 5.91, 6.78, and 9.98 mL g-1 for the whole-body of Chanos chanos. The concentration factors at steady state (CFss) of 137Cs for salinities of 26‰, 29‰, 32‰, and 35‰ were 6.23, 9.93, 9.24, and 6.86 mL g-1, respectively. After temperature exposure to 31°C, the fish gills showed hyperplasia of epithelial cells in branchial secondary lamellae, congestion of blood vessels, and hypertrophy of pillar cells. The fish from the treatment group exhibited hemorrhage between the branchial secondary lamellae and an abundance of mucous substance in comparison with control group. This study links radionuclide bioaccumulation data and monitoring data obtained in the field and laboratory experiment with radiation dose determined by ERICA Tools, an approach that will enable better linkages to be made between exposure and dose in Chanos chanos and its marine food web.Received: 2 November 2015; Revised: 1 July 2016; Accepted: 17 July 2016

An environmental radiation monitoring system that continuously measures gamma dose rate around nuclear facilities is an important tool to present dose rate information to the public or authorities for radiological protection during both normal operation and radiological accidents. We have developed such a system that consists of six GM-based device for monitoring the environmental dose rate around Serpong Nuclear Complex. It has operated since 2010. In this study, a description of the system and analysis of measured data are presented. Analysis of the data for the last five years shows that the average dose rate levels were between 84-99 nSv/h which are still lower than terrestrial gamma radiation levels at several other locations in Indonesia. Time series analysis of the monitoring data demonstrates a good agreement between an increase in environmental gamma dose rate and the presence of iodine and argon in the air by in situ measurement. This result indicates that system is also effective for an early warning system in the case of radiological emergency.

Hypocalcemia is one of manifestation of bone metastases which could be treated using calcium carbonate and cholecalciferol. Tc-99m radiolabeled 1,4,8,11-tetraazacyclo tetradecyl-1,4,8,11-tetramethylene phosponic acid(against 99mTc-CTMP)on the other hand is a radioactive complex compound which has an affinity toward bone. Therefore, it could be used as bone tracer (radiopharmaceutical) in bone imaging.However, there has been a concern regarding the use 99mTc-CTMPon patients who have been treated with calcium carbonate and cholecalciferol. In this circumstance 99mTc-CTMPcould interact withcalcium carbonate and cholecalciferol and it might then interefere with the imaging results. Therefore, the aim of this study was to determine the pharmacokinetic behavior of 99mTc-CTMP in rats (Rattus norvegicus)that had been previously treated with calcium carbonate and cholecalciferol. The pharmacokineticstudies were performed using four groups of animal modeland each groups consists of three rats. The groups were classified as control (I), rats treated with calcium carbonate (II), rats treated with cholecalciferol (III), and rats treated with both calcium carbonate and cholecalciferol (IV). After the rats were treated for 3 days,99mTc-CTMP radiopharmaceutical was injected through a tail vein of each rat. At specific time intervals after 99mTc-CTMP administration, blood wasthen extracted from the tail, weighedand counted using a single channel analyzer. The percentage of radioactivity in blood at a certain interval wasthen calculated to determine the distribution half-time and the elimination half-time. Thedistribution half-time of group I, II, II, and IV were 0.43+0.13, 0.25+0.18, 0.32+0.10, and 0.47+0.07 hours, respectively, while the elimination half-time were 2.56+0.18, 4.48+0.56, 4.47+1.13, 6.19+1.97 respectively. The results of T-test showed that there was no significant difference of distribution half-time between the three treated groups and the control group. However, there was significant difference of elimination half-time between the three treatment groups and control. This research showed that giving calcium carbonate or, cholecalciferol, and both for 3 days prior administration of 99mTc-CTMP would mantain elimination half-time which resulted in longer excretion/ elimination time.

Cervical cancer is the most frequent cancer found in Indonesia. The primary treatment of cervical cancer at the locally advanced stage is usually performed by using radiotherapy and chemotherapy. The combination of the two techniques is often called chemoradioherapy. The response to chemoradiotherapy is influenced by biological and physical factors. Major vault protein (MVP) is a ribonucleoprotein which contributes to drug resistance in some cancers. The purposes of this research were: (1) to determine the correlation between the expression of MVP and the index of p53, including AgNOR values and index of MIB-1; and (2) between MVP and chemoradiotherapy clinical response of cervical cancer. Twenty-one microscopic slides taken from biopsy tissues of cervical cancer patients before undergoing treatment were stained to identify MVP, p53, and MIB-1 by means of immunohistochemistry techniques and AgNORs staining. After undergoing chemoradiotherapy treatment, the patients’ clinical responses were observed by pelvic control method. Experimental results showed that there was a correlation between MVP and AgNOR value (P=0.05), but no correlation between MVP and index of p53 (P=0.729), including MIB-1 LI (P=0.63), in untreated cervical cancer. In addition, there was no association between MVP and chemoradioterapy response. In conclusion, MVP expression correlates with the process of cell proliferation before the G2 phase of cell cycle in untreated cancer cells. Those have no association with clinical responses after the completion of treatment.Received: 20 November 2013; Revised: 18 July 2014; Accepted: 28 September 2014
