One Fund Boston, the fund established to assist victims of the Boston Marathon bombing, has raised what its administrator, Kenneth Feinberg, described as an unprecedented figure for a fund of its kind, the Wall Street Journal reports.

As of last Thursday, the fund had raised some $46 million and received more than a hundred and fifty applications for assistance. By Monday, contributions had topped $51 million. According to a spokesperson for Feinberg, who has overseen or advised similar funds after high-profile tragedies such as the 9/11 attacks and mass shootings at Virginia Tech and Newtown, Connecticut, applicants for relief include the families of the four people killed in the bombings and their aftermath, at least fourteen people who lost limbs, and all the seriously injured.

The deadline for initial applications for assistance was Saturday, and the fund expects to begin paying out awards on June 30. Those who missed the deadline can still apply for compensation, but they won't be paid until after the first round of applicants receive checks.

According to the Journal, about $11.4 million was raised for the largest assistance fund created after the Newtown school massacres, $8 million after the Virginia Tech rampage, and more than $5.8 million after the Aurora, Colorado, movie theater shootings.

Unlike those who received funds from the September 11th Victim Compensation Fund, which awarded more than $7 billion in public money, recipients of assistance from One Fund Boston are not required to waive their right to sue potentially responsible parties in return for compensation. Those who suffered the loss of two limbs or permanent brain damage and families who lost a loved one will receive the biggest awards from the Boston fund, totaling perhaps as much as $2 million. The fund excludes those with purely psychological trauma, even though Feinberg acknowledged that a case could be made they should be included. "There is simply not enough money," he told the Journal. "You have to prioritize these claims."
