Radiation consists of the set of the electromagnetic waves which are emitted from the particulate matter of the space as we can say which involves the ionisation of the particles of the high energy. Thus, in the outside of the earth atmosphere there are cocoon of the radiations which come and hit the earth surface.it is the form of the energy that is emitted in the ray's electromagnetic waves or the particles. This form of the radiation can sometimes be seen as the visible light or even the ultraviolent light.my research is towards the reducing of the harmful radiations from interstellar space.

Relativistic Particles

The effects of the interplanetary magnetic field on the propagation of solar cosmic-ray particles are studied. The presence of the quasi-stable magnetic field of garden-hose type found by satellite observations suggests that the movement of the particles along these lines of force is much easier than that perpendicular to them. The diffusion equation of the particles through such a medium is solved, and the number density of particles at the earth is computed for several values of parameters. The results of the computation concerning the dependence of the time of maximum density on the position of the source relative to the sun–earth line are compared with those obtained from observations. It is found that the diffusion coefficient perpendicular to the line of force is 1/10 to 1/20 of that parallel to the line for relativistic particles, while the ratio is 1/50 to 1/100 for lower-energy particles.

AbstractSETI from space is currently envisaged in three ways: i) by large space antennas orbiting the Earth that could be used for both VLBI and SETI (VSOP and RadioAstron missions), ii) by a radiotelescope inside the Saha far side Moon crater and an Earth-link antenna on the Mare Smythii near side plain. Such SETIMOON mission would require no astronaut work since a Tether, deployed in Moon orbit until the two antennas landed softly, would also be the cable connecting them. Alternatively, a data relay satellite orbiting the Earth-Moon Lagrangian pointL2would avoid the Earthlink antenna, iii) by a large space antenna put at the foci of the Sun gravitational lens: 1) for electromagnetic waves, the minimal focal distance is 550 Astronomical Units (AU) or 14 times beyond Pluto. One could use the huge radio magnifications of sources aligned to the Sun and spacecraft; 2) for gravitational waves and neutrinos, the focus lies between 22.45 and 29.59 AU (Uranus and Neptune orbits), with a flight time of less than 30 years. Two new space missions, of SETI interest if ET’s use neutrinos for communications, are proposed.
