FAQ

Radon is an extremely volatile, colourless, odorless natural radioactive gas that is present in the air we breathe, it is a radio-produced gas that is produced from uranium and is found in small quantities in all types of earth and rock. Produced by three parent nuclides giving rise to three different radioactive families Thorio 232, Uranium 235 and Uranium 238. It is emitted from the ground and can accumulate in enclosed spaces, such as homes or workplaces. The amount varies according to local geology, it is measured in "bequerels" (Bq). A Bq corresponds to one disintegration per second. A concentration of 100 Bq/m3 therefore means that 100 atoms disintegrate every second in 1 m3 of the material or environment in question. The Radon (Rn) has atomic number 86, atomic weight 222, density 9.73 g/dm3, melting point -71  , boiling point -61.8  , oxidation states C. Discovered in 1900 as "emanation" of the radio, it was isolated in 1908 and called by W.Ramsay "niton"; the current name was given to him in 1923. The known isotopes are 20; the most important isotope, comes from radio, is 222Rn, which has a half-life of 3.823 days and is an alpha particle emitter. At room temperature it is a colourless gas; below the freezing point it is phosphorescent and yellow in color it turns red-orange at the temperature of the liquid air.

In the last 20 years, a series of international studies have highlighted its danger, so much so that the WHO has included it in group 1 of carcinogenic substances (maximum carcinogenicity). It is estimated to be the cause of 20% of lung cancer in Italy, second only to smoking by number of deaths caused. In nature it is found underground and in aquifers and , is generated continuously by some terrestrial rocks and in sedimentary rocks such as marl, flysh etc. may be highly harmful to health in high concentrations. The most common places where radon gas is contained are soil, water and building materials. It moves in the soil by convection or diffusion, clearly, because the radon moves, a certain permeability of the soil, some geological characteristics and the possible presence of water is necessary. For example, a gravelly or karst soil will allow good permeability, while a loamy soil, especially if with high humidity, could represent a natural barrier to radon gas leakage. It’s present in almost every region of Italy, although for the most part the levels are below the threshold. The NRPB (British National Radiological Protection Agency) recommends that radon levels in homes be reduced when the average level exceeds 200 Bequerels per cubic meter. This recommendation is promulgated by the European Union.

There are several proven methods to reduce radon levels in existing homes. The choice of method depends on the level of radon and the way the house was built. Since 1988, standards for the reduction of radon in new homes have been issued by various international organizations. Currently in Italy there are obligations only for workplaces by Legislative Decree 241/2000 which amended Legislative Decree 230/95. For residential environments and drinking water there are recommendations of the European Community of 21 February 1990: respectively 143790 LA 928/2001. The conference State Regions has also drawn up a document calling inter alia for the control of Radon called: Guidelines for the protection and promotion of health in confined environments.

Elexind has been collaborating for years with Gammadata AB, a leading international Swedish company for radon monitoring instrumentation and dosimetry. Passive Trace Dose Meters (CR-39) are available, both for short-term exposure (RAPIDOS 2.12 weeks) and for standard periods (3.12 months). The instrumentation includes the following instruments: Radon monitoring in air: Atmos 12 Radon monitoring in soil: Markus 10 Monitoring in air and water: GDM 20

STERLING Glove technology combines nitrile protection with latex sensitivity. The production process of these gloves increases the tensile strength, to further increase its barrier function. The process also allows a reduction in the thickness of the glove, so that less force is required to stretch the material. The result is a latex-free glove, but at the same time with the dexterity and sensitivity of latex. In addition, as 50% more gloves were added per package, the packaging is even more environmentally friendly. A customer using an average of 25 packages per month can save up to one ton of waste per year.

Yes, these gloves are created from a latex-free formulation, thus reducing the risk of allergic reactions to Type I latex proteins.

The nitrile formulation of the glove provides excellent durability and a protective barrier for low, medium and high risk situations (similar to latex). KIMBERLY-CLARK recommends vinyl gloves only in low risk situations.

The KIMTECH PURE G3 STERLING Nitrile gloves are recommended for cleanroom ISO Class 3 (Class 10) or higher category. The KIMTECH PURE G5 STERLING Nitrile gloves are recommended for cleanroom ISO Class 5 (Class 100) or higher category. Gloves differ in their level of cleanliness as regards particles, extractable substances and non-volatile residues.

No. Silicone is not used in the production of these gloves. In fact, gloves do not have traceable levels of silicone according to the most careful method used nowadays (FTIR - Fourier Transform infrared technology).

he KIMTECH PURE G3 & G5 STERLING Nitrile gloves have a higher tensile strength than the competitors. This is due to the patented manufacturing process that not only increases the tensile strength of the glove, but also allows for a reduction in mil thickness, thus allowing for a more durable and more comfortable glove.

AQL (Acceptable Quality Limit) of these gloves is 1.5. AQL refers to the probability of having defective gloves (for example, with micro-punctures) within a batch. The lower the AQL, The lower the probability of defective gloves. KIMTECH PURE G3 & G5 STERLING Nitrile gloves exceed ASTM standards - medical gloves standards - for their absence of micro-punctures and critical defects. ASTM standards are AQL 2.5 while our gloves have AQL 1.5. A low AQL for microphones is crucial - the fewer the number of microphones, the higher the level of protection barrier.

Yes, the gloves are static-dissipative. Both categories of gloves are tested with 3 different methods: Resistance with the person (ANSI/ESD SP15.1-2005), Volume Resistance (ANSI/ESD STM 11.12 - 2007) and Static Decay. The KIMTECH PURE G3 & G5 STERLING Nitrile gloves pass all 3 test methods.

The gloves have a very firm grip, making them a great choice for the semiconductor, flat screen, disc drive, pharmaceutical, medical device and biotech industries. The gloves have excellent grip on both wet and dry.

The glove has a textured structure on the fingertips to increase grip.

No. The only chemical interaction experienced by gloves is the normal chlorination process that removes residual dust and excess finish.

Yes. On average, the packaging configuration of the KIMTECH PURE G3 & G5 STERLING Nitrile gloves leads to a space saving of 33%. This means that you can keep the same safety reserve of gloves that you have at the moment, freeing up valuable space for other critical elements.

For a long time it was not possible to make devices and circuits on low-cost flexible substrates such as paper, PET and polyethylene film, as it was necessary to reach temperatures above 160 degrees Celsius, which such supports can not withstand. In recent years, however, innovative conductive inks and coatings containing nanoparticles of metals such as silver, gold or copper have been developed and marketed, making them highly conductive once sintered. These inks can be used with / screenprint inkjet printers that are well suited for printing on substrates such as paper, PET and polyethylene film, as the process takes place at room temperature. Today, with the UV pulse technology provided by Xenon Corp. it is possible to photosinter these inks without damaging the substrate on which they were deposited with a printing process. The intense pulses of UV light, with a duration of a few milliseconds, allow to heat only the inks, removing the solvent by evaporation, leaving on the substrate unchanged only the sintered metal of the nanoparticles. This process allows the sintering of conductive layers even from copper nanoparticles, with very high conductivity characteristics.
