Any nuclear reaction produce radiation hazard and should be guarded against by proper shielding.
If it's a pile of grass left on the lawn after you mow it, cal it a clump of grass.
This may be known as a scree slope or a talus pile. Talus and scree are normally used interchangeably, however scree normally refers to material of gravel size or smaller and talus to larger debris.

To calculate the effective overburden pressure on a pile toe, you would typically need to consider the weight of the soil above the pile toe that contributes to the effective stress. This can be calculated using the unit weight of the soil and the depth at which the pile toe is located. The effective overburden pressure helps determine the bearing capacity and settlement behavior of the pile.
The eccentricity of a pile is typically measured by determining the horizontal distance between the pile's centerline and the applied load or resistance. This measurement is crucial in structural design to ensure the pile can safely bear the intended loads without excessive deflection or failure. Eccentricity must be within specified limits to prevent structural issues or stability concerns in pile-supported structures.
The reactor power was a max of about 1/2 a watt. See http://www.cfo.doe.gov/me70/manhattan/cp-1_critical.htm for an account of the experiment. As far as radiation is concerned, this report does not give a figure, or even mention whether radiation was measured. The pile does not seem to have had any shielding, so the large group of observers as well as the experimental team would have had some radiation exposure, but limited in intensity and time. These were very early days, but the later reactors at Oak Ridge and Hanford had shielding.
This was built as part of the Manhattan Project in WW2, to demonstrate the principle of the chain reaction. The results were used to design the Hanford piles to produce plutonium. The chief scientist for the Chicago pile was Enrico Fermi, first criticality in 1942

Ionising radiation was discovered in Würzburg in Germany by Wilhelm Rontgen in 1885. This discovery led to nuclear power.

I wish that I could have found out. I believe Chicago would be a massive pile of ashes if he had lost. Too bad...... I wish that I could have found out. I believe Chicago would be a massive pile of ashes if he had lost. Too bad......
The first chain reaction was demonstrated in the Chicago 'pile', in 1942.

Enrico Fermi is often credited with creating the first nuclear reactor, known as Chicago Pile-1, in 1942. However, the development of nuclear power as a source of energy involved contributions from many scientists and engineers over time.
This was first achieved in the Chicago pile, 1942. Enrico Fermi was the team leader.
