An enemy of the health is invisible, frightful and quiet exists that appropriately is proliferated in closed environments. An inert gas denominated radon, which is product of uranium 238U, uranium 235U and thorium 232Th and is considered cancerigenic by the World Organization of the Health (WHO). By the abrupt climatic changes in the Puno zone (Macusani), the pupils of the schools are forced to study in closed rooms. Macusani is the most important district of Peru which produces uranium. Uranium disintegrates in its daughters 218Po, 214Pb, 214Bi, 214Po… 206Pb, which are radioactive and dangerous. For that reason the present work of investigation focuses on the calculation the concentration of radon, in educative environments and the impact that it generates on the students. This study was made in Macusani. The analysis (with techniques of gamma spectroscopy and canister of activated ch...

The Astrophysics Directorate of CONIDA has installed two radio spectrometer stations belonging to the e-CALLISTO network in Lima, Peru. Given their strategic location near the Equator, it is possible to observe the Sun evenly throughout the whole year. The receiver located at Pucusana, nearby the capital city of Lima, took data from October 2014 until August 2016 in the metric and decimetric bands looking for radio bursts. During this period, this e-CALLISTO detector was unique in its time-zone coverage. To asses the suitability of the sites and the performance of the antennas, we analyzed the radio ambient background and measured their radiation pattern and beamwidth. To demonstrate the capabilities of the facilities for studying solar dynamics in these radio frequencies, we have selected and analyzed type III Solar Radio Bursts. The study of this kind of burst helps to understand the e...
