Dosimetry forms an inseparable part of radiation processing. Many dosimeters are available to cover wide range of doses used in radiation processing. These include the Fricke, ceric-cerous, alanine ESR Alanine (Electron Spin Resonance Technique), dichromate, and radiochromic films. Low-dose radiation processing applications (<2 kGy) such as insect disinfestation, shelf-life extension, and sprout inhibition use imported dosimeters. At present, radiochromic films/waveguides are used for low-dose applications; however, the dosimeters are costly and subject to sanctions and supply restrictions from country of origin. The present work discusses the development of system that can be used as a routine dosimeter for radiation processing facilities in the dose range of 200–2500 Gy. Iodine is generated by the action of radiolysis products of water on iodide and iodate present. Generated iodine halogenates fluorescein to erythrosine with the help of bicarbonate. Increase in absorbance due to the formation of erythrosine can be related to the absorbed dose and used in routine dosimetric applications. As the change is radiochromic, it advantageously provides a visual indication of dose received.

Skin radiation exposure occurs during planned or unplanned radiation events, such as radiotherapy or nuclear radiation accidents, respectively, resulting into acute and chronic effects depending upon the extent of the radiation exposure or contamination. Radioactive nuclide-induced contaminations severely affect the human skin as skin is the largest organ of the body. Skin radioactive contamination may result into radiation-induced burns that may significantly cause morbidity without any medical intervention. In such scenario, it is necessary to provide priority to severe and life-threatening injuries. The current review provides a holistic picture about the mode of occurrence of radiation injuries, types of radiation burns, local skin effects and pathophysiology, prognosis, diagnosis and treatment, and challenges in the management of radiation wounds. Further, the review also includes the dressings used for irradiated wounds and comparison of amniotic and silver dressings, which possess potential bactericidal and wound-healing properties.

The sampling and measurement of airborne tritium is an essential component of workplace monitoring at heavy water handling facilities and nuclear reactors using heavy water as coolant and moderator. Tritium being an internal hazard, its workplace monitoring and assessment of internal exposure of workers is a regulatory requirement for the facility. The conventional tritium air sample collection methods are condensation, bubbling, and trapping with appropriate media such as dry ice, water, and desiccants, respectively. A novel method for rapid collection of moisture in the air for the estimation of tritium is presented and discussed in this article. It involves condensation of tritium oxide in the air using a commercially available thermoelectric cooling module which has removed uncertainty in the availability of dry ice or desiccant. The instrument is capable of collecting 2–3 ml of sample in 30 min at a relative humidity level of about 60% and temperature of about 25.5°C. The quantity of sample collected is sufficient for the estimation of tritium concentration in air. The Peltier module-based low-cost, simple, and reliable system has been successfully implemented for workplace tritium in air sampling at radiological facilities.

In this study, the weak alpha radiation sources and the beta radiation by the effect of them on the electrical conductivity of air inside the ionization chamber are studied by measuring the produced current. The aim of this study is to make an ionization chamber to measure the ionization caused by weak radioactive sources which produce the electrical current at the order of femto- to pico-amperes and try to estimate the ion recombination coefficient at low ion densities. A parallel-plate ionization chamber with proper shielding and noise reduction circuits are made which measure data and sent them to a personal computer by USB port. The current-voltage characteristics of the ion chamber are measured when different radioactive sources are placed inside the chamber at the different separation of electrodes. The recombination constant obtained is estimated equal to 1.18 × 10−6 cm3/s. It is shown that current-voltage characteristic for ion chamber with different electrode separation lies on a unique curve by a proper normalization in the pico- and femto-ampere current range.

Center of Plasma Physics-Institute for Plasma Research, Nazirakhat, Assam, has the neutron source based on Inertial Electrostatic Confinement of Fusion. In order to scale up the source, it is planned to build a neutron source facility. The facility needs the construction approval from AERB India for occupational radiation safety during the operation and after the operation. It will also assess the short-term and long-term radiological hazards due to the neutron source. In order to evaluate the post irradiation radiation hazards due the neutron source, the radioactivation analysis of laboratory is carried out and reported here. The radioactivity in the laboratory building and source components after short-term and long-term operation has been assessed. The tritium activity in the soil is also evaluated. The calculation is also done for the contact dose rate estimations after operation to assess the maintenance applicability inside the laboratory. The inhalation dose inside the laboratory after the operation has been also calculated to avoid any hazards after operation maintenance activities. The article provides the complete details of post operation hazards analysis for the Inertial Electrostatic Confinement Fusion neutron source facility.

Understanding of extreme weather conditions at the site of interest is essentially required in the design of engineering structures so that the structures can withstand weather stresses. This paper presents an analysis of extreme values of meteorological elements observed at Narora site for the last three decades (1989–2019). The elements considered are extreme air temperature (°C), minimum relative humidity (%), extreme wind gust (km/h), maximum rainfall (mm) in a day and a month, and annual rainfall. The extreme value analysis reveals that the maximum air temperature, maximum wind gust at 30 m, maximum monthly rainfall, and maximum annual rainfall obey Fisher-Tippett Type-1/Gumbel extreme value distribution, whereas minimum air temperature, minimum relative humidity (%), annual daily maximum rainfall (mm), and annual minimum rainfall (mm) obey Fisher-Tippett Type-2/Frechet extreme value distribution function. Distribution function parameters, i.e., location, scale, and shape parameter for each variable, have been determined. Extreme values corresponding to return periods of 50, 100, and 1000 years are worked out using best fit linear regression curve as a compliance of the Atomic Energy Regulatory Board Safety Guide Recommendations. The derived extreme values are particularly useful to designer for arriving at suitable design basis values of different elements to ensure the safety of the reactors and other civil structures in Narora region, with respect to stresses due to weather conditions. Extreme values corresponding to return periods of 50 and 100 years at Narora are compared with corresponding values at other three nuclear reactor sites in India, namely, Tarapur, Kalpakkam, and Trombay. In addition, the time series pattern analysis of rainfall for 31 years at the Narora site closely following the 2-year moving average rainfall data pattern. These results can be used for water harvesting, irrigation, and floods management plans in the future.

Studies on foliar uptake of tritiated water (HTO) on Spinach sp. during light and dark condition was simulated inside the environmental chamber, and an attempt was made to compute CTFWTHTO, CpfwHTO, CpcwOBT, CpfwOBT using basic equations available in IAEA TECDOC1616. The predicted activity was compared with the observed activity. The conversion of tissue-free water tritium (TFWT) to organically bound tritium (OBT) was more in the light condition. The ratio of OBT to TFWT varied from 0.006 to 0.082. The ratio of observed OBT activity (Bq/kg fresh weight) in light to dark conditions varied from 34% to 117%.

The present investigation is an attempt to trace the heavy metal enrichment in the soil matrix of the wetlands Kannur district, Kerala. Wetland is an ecosystem which plays significant role in ecological balance. Characteristic vegetation of aquatic plants makes this distinct ecosystem as unique and distinguishable from other land forms and water bodies. The hydric soil prevailing in the wetlands is rich in organic matter content and also enriched with many heavy metals. In view of this, the enrichment of some major heavy metals such as Co, Fe, Mg, Cu, Zn, Cd, Hg, Ni, Pb, and As have been quantified in the soil samples collected from the wetlands of southern part of Kerala using Inductively Coupled Plasma-Mass Spectrometer. The adverse effect of this enrichment on human and environment is of serious concern and hence various pollution index parameters were calculated to assess the extent of contamination. The spatial distribution study confirms the dependence of geological factors on the enrichment of heavy metals. The study on various pollution index parameters reveals the selective enrichment of heavy metals. The continuous monitoring of wetlands is the need of the time as such areas are preserved for the cultivation of aquatic plants. The results of the investigation are presented and discussed in detail in the manuscript.
