Physics2D.OverlapCircleAll and method call cause a huge drop in animation frames

I am preparing a 2D game I want to cause a surface explosion with damage / destruction of objects within the circle I am using Physics2D.OverlapCircleAll and method call this cause a huge drop (in Profiler included in the category - Others). Can I ask for a hint on how to solve this problem?

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class ShellDestroy : MonoBehaviour { private Vector3 explosionPos; [SerializeField] private float radius=30.0f; BuildingDestructionController DestControl; void Start() { explosionPos = this.transform.position; } void Explode2() { Collider2D[] hit = Physics2D.OverlapCircleAll (explosionPos, radius); foreach (Collider2D c in hit) { if (c.GetComponent()) { c.GetComponent().TakeDamage(200); } } } void OnCollisionEnter2D (Collision2D coll) { Explode2(); } }

The TakeDamage method deletes several objects (2-10):

private void DestroyStructure() { if (DestroySound != null) DestroySound.Play();

     GetComponent<BoxCollider2D>().enabled = false;

     if (DamagedSprite != null)
         DamagedSprite.enabled = false;


     if (DestroyedSprite != "")
     {
         GetComponent<SpriteRenderer>().sprite = DestroyedSpriteList[Random.Range(0, DestroyedSpriteList.Length)] as Sprite;
         //GetComponent<SpriteRenderer>().color = new Vector4(1, 1, 1, 0.5f);
         GetComponent<SpriteRenderer>().sortingOrder = 1;
         GetComponent<SpriteRenderer>().sortingLayerName = "Background";
         mat_tree = new Material (Shader.Find ("Sprites/Default"));
         gameObject.GetComponent<Renderer>().material = mat_tree;
         AstarPath.active.Scan();
     }

     else if (DestroyedSprite == "")
         GetComponent<SpriteRenderer>().enabled = false;
     if (Particles != "")
         particles.Play(includeChildren);
 }
 public void TakeDamage (int amount) {
     if(isDestroyed==true)
         return;
     HP -= amount;
     Strength -= amount;
     if (HP <= 0 || Strength <= 0) {
         ps.Play(includeChildren);
         playeddest = true;
         //isDestroyed==true;
         DestroyStructure();
     }
 }
