In not too many orbits, that eccentricity in our orbit might pull us into the Van Allen belt.

In science:

However, it is a very severe environment for the spacecraft because such an orbit passes through the inner Van Allen belt twice per revolution.

Spacecraft electronics are subject to space radiation hazards. The space radiation environment includes trapped electrons and protons of the Van Allen radiation belts, and non-trapped, transient solar and galactic cosmic rays and solar flare particles.
Spacecraft Charging and Hazards to Electronics in Space
Stassinopoulos and Raymond, 1988). The trapped radiation environment includes the Van Allen radiation belts and consists of electrons, protons and some heavy ions and is influenced greatly by solar terrestrial interactions and the South Atlantic Anomaly (SAA).
Spacecraft Charging and Hazards to Electronics in Space
The Van Allen radiation belts consist mainly of electrons and protons.
Spacecraft Charging and Hazards to Electronics in Space
Figure 9 (Strassinopoulos and Raymond, 1988) shows the electron and proton distributions in different regions of the magnetosphere. As shown in that figure, the energetic Van Allen belt electrons exist in two distinct regions: the "inner zone" and the "outer zone".
Spacecraft Charging and Hazards to Electronics in Space
The Van Allen radiation belts showing electron and proton densities (after Anspaugh et al., 1982; Cladis, 1971).
Spacecraft Charging and Hazards to Electronics in Space
After launch in August 1989, the pro ject suffered a ma jor setback: the apogee boost motor failed to ignite, and the satellite was left in an unintended elliptical transfer orbit, at the mercy of a twice-daily immersion in the Van Allen radiation belts.
